Installation of the Director VDA Plug-in Failed with Error Code 1603


Rob Mullens1709157194

Question

Seeing this and easily reproducing it in our environment. 

When the VDA is installed, not all components are being installed.  The one that fails is the Director VDA Plug-in.

The part of the installation for the plug-in that fails is when it is calling the .NET Framework to register the COMServer.

MSI (s) (B4:E4) [14:26:57:142]: Executing op: CustomActionRollback(Action=Rollback_RegisterComServer,ActionType=3362,Source=C:\Program Files\Citrix\Virtual Desktop Agent\,Target=C:\Windows\Microsoft.NET\Framework64\v4.0.30319\regasm.exe /silent /unregister DirectorComServer.exe,)
CustomAction Rollback_RegisterComServer returned actual error code -1073741819 but will be translated to success due to continue marking

 

Attempting to repair .NET does not result in allowing the install to complete, nor does uninstalling of all Visual C++ Runtimes and reinstalling them.

 

This is happening on systems that have had the VDA removed either via Uninstall from the Programs and Features control panel snap-in or via the VDACleanupUtility.

 

Is anyone else out there experiencing this, or have an idea on what can be done to overcome this?

Found the answer and I feel like an idiot for it.

 

Our corporate AV product is Symantec Endpoint Protection.  We had also deployed CrowdStrike Falcon Sensor some time late in the fall.  Our Cyber Security group had informed us that CrowdStrike was only in "monitor" mode and not scanning anything. 

This has turned out to be false. 

The entire issue is due to Symantec and CrowdStrike attempting to perform application control at install time when the COM Server is attempting to be unregistered or registered.

Should include additional information.

Windows 10 1903 and 1909 are seeing this.

.NET Framework 4.8 is installed

The installation media being used is the VDAWorkstationSetup_1906_2 and VDAWorkstationSetup_1909.

The previous versions that have been installed are 7.15 CU4, 1808, and 1811.

In addition, going back to an older version of the VDA results in the same error.

In MSI Logs below is Error Msg I found based on Windows Installer

 

MSI (s) (2C:40) [09:56:55:629]: Product: Citrix Director VDA Plugin -- Error 1722. There is a problem with this Windows Installer package.

Try this:

 

1. Disable and stop the WMI service.

     sc config winmgmt start= disabled

     net stop winmgmt

 

2. Run the following commands.

     Winmgmt /salvagerepository %windir%\System32\wbem      (I noticed that you have run this command, but I would suggest that you try it again)

     Winmgmt /resetrepository %windir%\System32\wbem

 

4. Re-enable the WMI service and then reboot the server to see how it goes.

     sc config winmgmt start= auto

 

If the problem remains, then try the following steps to rebuild the repository:

 

1. Disable and stop the WMI service.

     sc config winmgmt start= disabled     (note that there is a blank between '=' and 'disabled')

     net stop winmgmt

 

2. Rename the repository folder (located at %windir%\System32\wbem\repository) to repository.old.

 

3. Re-enable the WMI service.

     sc config winmgmt start= auto

 

4. Reboot the server to see if the problem remains.
