Product: ProfileUnity-FlexApp

Product Version: 6.7.0

Expires on: 365 days from publish date

VirtFsService.exe would crash during Logon with DIA applications present in windows 7 or windows 10 desktop. This could happen anytime during the session thus making DIA applications dispensary.

Possible Resolution(s):

On the master image please edit those files: 

  • C:\Program Files\ProfileUnity\FlexApp\ContainterService\x64\VirtFsService.exe.config
  • C:\Program Files\ProfileUnity\FlexApp\ContainterService\x86\VirtFsService.exe.config

Remove these two lines from "CloakRoots" section of configuration file:


Save the file.

Lines to delete:


Recompose the pool. If there is no ProfileUnity on the master image than modify those files to remove lines listed above:

  • \\\NETLOGON\LM-ProfileUnity6\\ContainerService\x64\VirtFsService.exe.config
  • \\\NETLOGON\LM-ProfileUnity6\\ContainerService\x86\VirtFsService.exe.config

Note: This fix will be rolled in to next version of ProfileUnity (6.7.5)
