UE-V Template Generator Error

Related to: ADK 1703, 1709, 1803, 1809

After installing the UE-V Template generator it throws an error when you try to create a custom template. In the following example I’m trying to create a template for 7ZIP.

Clicking Next triggers the UAC.

After confirming the UAC window with Yes, following error appears.

Additionally, the SCM writes an event error 7000 to the system log.

This happens because the UE-V generator is temporarily installing the AppV monitoring service to keep track of the application’s changes. Unfortunately the AppV monitor service image file (AppVMon.sys) file has been signed using a legacy signing method. You can doublecheck this by viewing the signature tab of the file (located in C:\Program Files (x86)\Windows Kits\10\Microsoft User Experience Virtualization\Management if the default paths have been used for installation).

If it shows 2 digest (sha1 and sha256), the file is signed using an old signing method. Correctly signed files should only show the sha256 digest.


You can still use the template generator but you have to disable secure boot in UEFI and switch Windows into testsigning mode to ignore driver signing errors. To do so, follow these steps:

  • Disable Bitlocker (if used) by opening an administrative powershell and typing following command:

Suspend-Bitlocker -MountPoint C: -RebootCount 3

  • Shut down your PC, enter UEFI setup utility and disable secure boot.
  • Boot your PC and enable testsigning mode by opening an administrative command prompt and typing following command

bcdedit /set testsigning on

  • Reboot and run UE-V template generator
