This article explains the steps need to be followed to install Capture Client on VDI

For VDI master image with Capture Client and without VDI configuration

• Uninstall Capture Client.  This should Uninstall both Capture Client and the SentinelOne agent. Verify that the machine is not reported in unmanaged devices
• Confirm both CC & S1 are uninstalled
• Reboot – this is needed to fully Uninstall the CC & S1 kernel-level drivers.
• Follow instructions as given in the above section based on your chosen SentinelOne Version

For VDI master image without Capture Client 

For SentinelOne versions up to and including 3.0.*

• Install Capture Client on the VDI master Image using the command line with VDI_MASTER=1 flag:     
  C:\> msiexec /i "SonicWall Capture Client.<version>.msi" VDI_MASTER=1
• Let Capture Client completely install and install SentinelOne. 
• Once everything is all green and fully installed, SentinelOne recommends that you make sure the full disk scan is completed.  
  NOTE: If you make the clones while the master runs the scan, there will be unexpected results on the new VMs.
• You can verify the scan status by checking the Capture Client device details page in the management console.  highlighted in Orange
• Once the scan is completed, shut down the master VM image.

Once the master VM image is shutdown you can clone it. 

For SentinelOne versions 3.1 to 3.3.2:

• Install Capture Client on the VDI master image
• Let Capture Client completely install, and install SentinelOne. 
• Once everything is all green and fully installed, SentinelOne recommends that you make sure the full disk scan is completed.  
  NOTE: If you make the clones while the master runs the scan, there will be unexpected results on the new VMs.
• You can verify the scan status by checking the Capture Client device details page in the management console.  (highlighted below in Orange)

• Once the scan is completed, follow the below

• Open the Command Prompt with Run as administrator.
• Navigate to the folder of exe: 
  "C:\Program Files\SentinelOne\Sentinel Agent version\"
• Run: sentinelctl.exe agent_id -r -b -k "<passphrase>"
• Run: sentinelctl.exe agent_id -v

• To get the SentinelOne passphrase
  • Export device lists from capture client

• In the exported CSV find the master image device and use the value in the ‘S1 Passphrase’ column.

• Make sure the output shows: Randomize UUID on next boot: true
• If the output is not true, repeat the steps of this procedure.

NOTE: If you do not do this, your Agents will not generate unique IDs and will result in duplicate entries and license consumption. Every Agent must have a unique ID to function.

• shut down the master VM image.
• Once the master VM image is shutdown you can clone it. 

For SentinelOne versions 3.3.3 and above:

• The /VDI installation switch is now supported again. It is recommended for VM environments that use Cold cloning. 
  • C:\> msiexec /i "SonicWall Capture Client.<version>.msi" VDI_MASTER=1
• If the sentinelctl.exe agent_id -r -b  command works well in your environment, continue to use that method.
