This page assumes the Enterprise Layer Manager has already been imported and configured. See Create and update the OS Layer in Unidesk 4. George Spiers for Hyper- V and Pv. S focused instructions. Layers Overview. A Technical Overview of Citrix Application Layering – 2. Citrix whitepaper. Enterprise Layer Manager (ELM) uses several types of layers: Operating System Layer. Platform Layer. Application Layer. Image Template. User Layer. The master versions of all Layers are stored inside the Enterprise Layer Manager virtual appliance. Citrix CTX2. 25. 95. Layering Best Practices. Operating System Layer. Operating System Layer is just the base OS (with patches) and VMware Tools. Other components are usually installed in Platform and Application Layers. If you install . NET Frameworks in the OS Layer, then you only need to run Windows Updates on the OS Layer. However, Office should always be installed in an Application Layer. Windows Store apps should be removed from the OS Layer, not other layers. Platform and Application Layers are tied to the OS Layer – The remaining layers (Platform and Application) are created from an OS Layer. These layers are linked to one OS Layer, and can’t be used on any other OS Layer. If you upgrade the hypervisor tools in the OS Layer, then you might have to recreate the Platform Layer. Only OS Layer captures changes to local groups and local apps – Any application that creates local users (e. Xen. App 6. 5) should be installed in the OS Layer. Platform Layer and Application Layers do not capture changes to local groups or local users. Platform Layer is the highest priority layer and should contain the following: (from CTX2. Considerations When Creating a Platform Layer in Citrix App Layering 4. Citrix Virtual Delivery Agent, or VMware Horizon Agent. Citrix Provisioning Services Target Devices Software. NVIDIA Drivers. Join the Domain. Citrix Receiver – for the Single Sign- on Component. Citrix Workspace Environment Management Agent. Imprivata. Hypervisor Tools – if packaging or publishing to a different hypervisor than originally used to create the OS Layer. SAM database changes (local users, local groups) are not captured in the Platform Layer. You might have to use group policy to create and populate local groups. For example, Citrix Virtual Delivery Agent creates local users adds domain users to local groups. See Direct Access Users Group Missing All Layers at Citrix Discussions. Domain Join in Platform Layer does not capture adding Domain Admins to local Administrators group and Domain Users in the local Users group. Use Group Policy Restricted Groups or Group Policy Preferences Local Users and Groups to add these Domain Groups to the Local Groups. Here are some additional settings in a Group Policy at Computer Configuration > Preferences folder > Control Panel Settings Right- click the Local Users and Groups node, point to New, and select Local Group. Action – Update – Group – Remote Desktop Users – Add Members “DOMAIN\Domain Users”Action – Update – Group – Remote Desktop Users – Add Members “NT AUTHORITY\Authenticated Users”Action – Update – Group – Performance Log Users – Add Members “NT Service\Citrix. Telemetry. Service”Action – Update – Group – Performance Monitor Users – Add Members “NT Service\Broker. Agent”Action – Update – Group – Administrators – Add Members DOMAIN\Your_Citrix_Admins_Group. Action – Create – Group – Anonymous. Action – Create – Group – Direct Access Users – Add Members DOMAIN\Your_User_Group. Windows 1. 0 apps should be removed from the OS Layer, not from the Platform Layer. An Image Template (the composed machine that is published to the hypervisor) can contain only one Platform Layer. If you are creating a Platform Layer for Citrix Provisioning Services, then that one Platform Layer should include both the Citrix VDA, and the Citrix Pv. S Target Device Software. Application Layers. Application Layers contain anything not in the OS Layer or Platform Layer, including the following: Applications. Antivirus. Print Drivers. SCCM Client. Per- user settings (profile changes) are not captured in an Application Layer. When creating a Layered Machine, there are two methods of merging the Application Layers: Pre- boot – ELM merges the App Layers with the OS Layer and Platform Layer to create a single monolithic disk file. This method provides the greatest application compatibility. Use this method for Apps with boot time services or drivers. Elastic – When the user logs into a Layered Machine, a service looks in a file share for any Elastic Layers assigned to the user, and merges (mounts) them as the user logs in. Different users can have different Elastic Layers, even on multi- user Remote Desktop Session Host (Xen. App) machines. However, Elastic Layering doesn’t work for apps that need boot- time services/drivers. A single App Layer can be merged using either of these methods. If the App Layer doesn’t work Elastically, then you can mount it Pre- boot (Image Template) instead. There is no need to create separate App Layers for each mounting method. Elastic App Layers are stored in a SMB file share. You can use any desired method to provide High Availability for this file share, including: Scale Out File Server, DFS Namespace/Replication, etc. FSLogix creates local groups every time the service restarts. Thus it works when installed inside an Application Layer. Image Template. Image Template contains one OS Layer, one Platform Layer, and zero or more App Layers. The App Layers assigned in the Image Template are merged pre- boot. You then Publish the Image Template to your hosting platform. For MCS, the Template is pushed to a hypervisor (e. Sphere) virtual machine, which becomes the master image for an MCS Catalog. For Pv. S, ELM creates a VHD file, and pushes it to a Pv. S v. Disk Store, so you can assign it to Target Devices. For Elastic Layers, you must enable Elastic Layers in the Image Template. User Layers. User Layers allow users to install their own applications. In ELM 4. 5, User Layers are a lab feature. User Layers require additional consideration for backup, replication, and recovery. User Layers are tied to OS Layer – From Gunther Anderson at User Layers with New OS& Platform Layer at unidesk. Like App and Platform Layers, User Layer disks are tied to the OS layer they were originally built from. If you have a user login to images from two different OS layers, you will see the User Layer disks in two different directories on the share, one for each OS layer. The image itself knows what OS layer it was built from, and the ULayer service uses that information.”If you want profile portability, store the profile outside of the User Layer by implementing Citrix Profile Management. The default size for User Layers is 1. GB. You can change this size by setting HKLM\Software\Unidesk\Ulayer\Default. User. Layer. Size. In. Gb on the managed machines.

NET Frameworks go in the OS Layer. Store apps are removed from the OS Layer. Keep the layer as clean and as small as possible. A packaging machine will not be part of your domain. Delete any installers from the desktop, delete any temp directories, and empty the recycling bin. If Windows Updates, delete the contents of C: \Windows\Software. Distribution\Download. Underlying applications should be layered first, and then selected as prerequisite layers when you go to create a layer for the subsequent application. Use Application Layer Recipes. Turn off the application’s auto- updater. For antivirus, follow the manufacturer’s steps to “generalize” or remove any unique client identifiers. Handle application licensing – rearm, activation, etc. Run ngen. exe update. Also see Citrix CTX2. Layering Best Practices: Operating System Layer. Application Layers are tied to the Operating System Layer. ELM automatically upgrades OS Layer drivers. However, OS Layer Scripts should be updated reinstalling the Machine Tools. NET should be in the OS Layer. OS Layer is lowest priority. Patch OS by creating an OS Layer Version. When patching, ensure Windows is activated. VMware Tools goes in the OS Layer. Update it too. Windows Store apps should be removed from the OS Layer. Application Layers. Per- user profile settings are not captured. Local users and local groups are not captured. Unattended/Silent Installation Switches for Windows Apps. Introduction. The goal of this document is to collect instructions for performing unattended /. Such instructions. A quick word on terminology: Strictly speaking, an unattended. However, most people use these terms. Here, we are interested not only in performing unattended installations, but. This is necessary for reliably installing multiple. General information. There are several systems which vendors use to create installers for their. To make an educated guess about how to run an installer unattended. Sometimes this will be. Of course, you can try running the installer with the /? But if you really expect this to work. Windows for very long. In my experience, the odds. MSI packages. Microsoft's own Windows Installer Service is the nominal standard, and if. Unfortunately. Microsoft invented it too late. The package files have a . For installation, use the /i and /qb switches. Use the. /l* switch to produce a log file. You can provide named options (or. For example, this command. Active. Perl. msi PERL_PATH=Yes PERL_EXT=Yes. Active. State Perl, instructing the MSI package to add. Perl. exe to your PATH and to associate . Perhaps the most important common property is the REBOOT property, which you can use to suppress any automatic. MSI package might try to perform. So in general, you want to provide. REBOOT=Really. Suppress. Neat, huh? Too bad nobody uses it. Install. Shield. Install. Shield is one. of the oldest and most widely used application packaging systems. Installers created by Install. Shield recognize the /r, /s, /sms, /f. The installer itself is invariably named setup. To perform a silent installation, you need an Install. Shield "answer. file", customarily named setup. Some applications ship with. Here is how it works. Run the installer with the /r. Proceed through the dialogs and complete the. This will create a setup. C: \WINDOWS directory (yes, really). This file will include all of. Install. Shield dialogs, allowing you to perform unattended. Simply copy setup. Once you have a setup. This will perform an unattended. Unfortunately, the installer will fork a separate process and exit, meaning it. This makes it useless for scripting purposes. Luckily, there is another switch. Hence, for an Install. Shield application, you want to provide both the /s and the /sms switches. The /f. 1filename switch allows you to specify a. Note that. there must be no space between the /f. This switch works both with /r to create the file and. The /f. 2filename switch specifies a log file. Once again. there must be no space between the switch and the file name. WARNING: Be careful what characters you use in these file. Install. Shield silently strips certain non- alphanumerics (like. Oh, one more thing. The /r and /s switches only work. Many packages have "custom. For such packages, I suggest. If that does not work, I suggest doing. Packageforthe. Web. Install. Shield has a relatively new add- on product. Packageforthe. Web, or PFTW for short. This is basically an Install. Shield. tree bundled up as a single- file executable. When you run this executable, it extracts a bunch of files to a temporary. The PFTW package recognizes the /s and /a .. The /s switch instructs the PFTW package to run silently. The /a .. ("add") switch allows you to add switches. You may. provide any of the normal Install. Shield switches here, including /r. Thus, to automate the installation of a PFTW package named foo. Then, to install the package completely silently, you would run. The first /s is only needed for a completely silent installation. If you leave it off, the PFTW package will show you a status bar as it extracts. Install. Shield tree to the temporary directory. Install. Shield with MSIRecent versions (7 and above) of Install. Shield's tools are able to produce MSI files. Read Install. Shield's documentation for full details. These MSI files may be shipped alone or with a setup. These installers in turn come in two flavors, called "Install. Script. MSI" and "Basic MSI". Install. Script MSI uses the traditional Install. Shield switches. Basic MSI is. To perform an unattended installation using a Basic MSI installer, you provide. These should include the /qb (or /qn) switch to make. Just to make things interesting, any of these mechanisms might be combined with. PFTW. For example, we eventually figured out that the IBM Update Connector requires these flags for unattended. The first /s tells the PFTW installer to extract silently. The. /a tells it to provide the remaining switches to the underlying. The second /s tells setup. Finally, Install. Shield has a Knowledge. Base article which is less helpful than you might. Are we having fun yet? Wise Install. Master. Install. Master from Wise. Solutions is a competitor to Install. Shield. You can usually identify the. Wise". Install. Master installers are supposed to recognize the /s switch to. And in our experience, they generally do. But. there is no way to set options, and the exit status is meaningless. Note: This product has been rebranded the "Wise. Installation System". Don't let them confuse you. Inno Setup. Inno Setup is. You can usually identify the installers. Inno". The switches for Inno Setup are fully documented in the ISetup. Inno distribution. Here, is an html version. Thanks to. Lawrence Mayer for it. In our experience, the /silent switch is usually sufficient for a. But to be completely sure, we recommend /sp- /silent /norestart. Note that the /verysilent switch may reboot the machine without. So if you use. /verysilent, be sure to use /norestart as well. Nullsoft Scriptable Install System. The Nullsoft Scriptable. Install System (NSIS) is another open source installation system. It was. created by the Win. Amp authors. to distribute that application, but it is now a general- purpose system which anyone might. When an NSIS installer runs, it creates a little window which says verifying installer: N%, where N counts from 0 to. So you can recognize these installers by this behavior. Actually the. verification procedure is optional, but most installers have it enabled. As an. alternative, you can run "strings" and grep for "NSIS"). NSIS installers recognize /S for silent installation. NCRC to suppress the CRC (verification) step, and /D=dir to specify the "output directory", which is where the. These options are case- sensitive, so. Incidentally, all /S does is change the installer script's Silent. Install attribute from "normal" to. What effect this has, exactly, depends on the person who. If /S does not perform a silent install, consider. Ghost installer. Ethalone's Ghost installer. The free edition is nothing but the compiler, which takes XML files; the. XML files. When a Ghost installer runs, it creates a little graphical window which says. Ghost installer wizard. Setup is preparing the Ghost Installer. Ghost installers recognize - s (case- sensitive) for silent. If you have trouble to get it silent you might try to guess internal variables. My. Var=value. Unfortunately, using "strings" will not help you. See here. Other command line parameters are - r (repair). Microsoft hotfixes and older packages. Most Microsoft hotfixes respond to the /? According to KB. article 8. KB article 8. 24. Microsoft is moving towards standardized. But they are not done yet. Modern hotfixes support /passive (formerly /u) for. Some hotfixes use an old Microsoft packaging technology called. IExpress", whose switches are more- or- less documented in KB article 1. USENET post. These installers first extract some stuff. They. support the /t: path switch to specify the temporary. Specifying just /c suppresses running the command at. These packages support the /q switch for quiet operation, except. They also support the /r: n switch to suppress the reboot. Sometimes these do not work and you. NOTE" in KB article 3. Leave it to Microsoft to make systems administration an experimental science. If all else fails.. If the application simply has no unattended installation procedure, you can. I prefer to avoid these approaches if at all possible, since. Repackaging. There are several tools around which can take a snapshot of a machine's state. The Wise product line provides good support for this, and Microsoft's free tool provides bad support for it. The problem with this approach is that it fundamentally cannot work reliably. An. installer's behavior may depend on the exact initial state of the machine, such. OS version or the presence/absence of other installed software.
