If you plan to use the Full User Layer to save the state of non-persistent virtual machines, you must do the following before installing the Light Agent on a virtual machine template:

1. Create the file C:\Program Files\Unidesk\Uniservice\UserExclusions\KESLA.txt and add the following exclusions to it:
   • C:\ProgramData\KasperskyLab\
   • C:\ProgramData\Kaspersky Lab\
   • C:\Program Files (x86)\Kaspersky Lab\
2. Make the following changes to the operating system registry:
   1. In the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Unifltr registry key, create a new DWORD key with the name MiniFilterBypass and the value 1.
   2. In the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Unirsd registry key, create a new MULTI_SZ key with the name ExcludeKey and the value \Registry\Machine\SOFTWARE\WOW6432Node\KasperskyLab.
3. Restart the virtual machine.

To install on virtual machines in an infrastructure that uses Citrix App Layering technology, you need to do the following:

1. Install Kaspersky Security Center Network Agent and Light Agent for Windows on a virtual machine template on the Application Layer.
2. Create a multi-layer virtual machine image.
3. Deploy the created image to hypervisors that support Citrix App Layering.
4. Configure creation of non-persistent virtual machines from the created image.

For more information on installing antivirus software with Citrix App Layering, refer to Citrix App Layering documentation.

To ensure that Light Agent for Windows is compatible with Citrix Provisioning technology (Citrix Provisioning Services), you must perform the following steps:

1. If Citrix Provisioning Target Device software is installed on the virtual machine, it must be removed before you begin installing Light Agent. After completing the installation of Light Agent, you need to install the Citrix Provisioning Target Device.
2. Light Agent for Windows must be installed in one of the following ways:
   • Using the installation wizard Select the Ensure compatibility with Citrix PVS check box in the Advanced settings step.
   • Remotely via Kaspersky Security Center. Select the Ensure compatibility with Citrix PVS check box in the installation package settings.

Before installing on a virtual machine template, you need to create the file %SVAgent%\Config\Custom\snapvol.cfg and add the following exceptions to it:

• exclude_path=\ProgramData\Kaspersky Lab
• exclude_path=\ProgramData\KasperskyLab
• exclude_path=\Program Files\Kaspersky Lab
• exclude_path=\Program Files\Common Files\Kaspersky Lab
• exclude_path=\Program Files\Kaspersky Lab
• exclude_path=\Program Files (x86)\Kaspersky Lab
• exclude_path=\Program Files (x86)\Common Files\Kaspersky Lab
• exclude_process_path=\Program Files (x86)\Kaspersky Lab
• exclude_process_path=\Program Files (x86)\Common Files\Kaspersky Lab
• exclude_process_path=\Program Files\Common Files\Kaspersky Lab
• exclude_process_path=\Program Files\Kaspersky Lab
• exclude_process_name=avp.exe
• exclude_process_name=klnagent.exe
• exclude_registry=\REGISTRY\MACHINE\SOFTWARE\Wow6432Node\KasperskyLab
• exclude_registry=\REGISTRY\MACHINE\SOFTWARE\KasperskyLab
• exclude_registry=\REGISTRY\MACHINE\SYSTEM\CurrentControlSet\Services\klupd_klif_arkmon
• exclude_registry=\REGISTRY\MACHINE\SYSTEM\CurrentControlSet\Services\klupd_klif_klark
• exclude_registry=\REGISTRY\MACHINE\SYSTEM\CurrentControlSet\Services\klupd_klif_klbg
• exclude_registry=\REGISTRY\MACHINE\SYSTEM\CurrentControlSet\Services\klupd_klif_mark
• exclude_registry=\REGISTRY\MACHINE\SYSTEM\CurrentControlSet\Services\klupd_klif_swmon
