Problem mounting images after ADK 11 upgrade

Adam Postgate 1 Reputation point

since updating to the latest ADK and WinPE (to support/test with Windows 11) I am unable to "update" the deployment share. I just get a message stating "Unable to mount the WIM, so the update process cannot continue"

We're running the latest MDT already, on server 2019.

I've tried multiple uninstalls/reinstalls, with and without a reboot in between.

I've also checked the imagepath registry key for the wimmount service.

Any suggestions as we can't seem to get anywhere?

    Hello @Adam Postgate

    Try and mount the wim manually with imagex. If you get an error with access denied or file not found then it is most likely a antivirus program blocking the acces.

    Also, check if the WIM and the ADK has the same build version of Windows, if not, it will fail to mount.

    Hope this helps with your query,
