I've been working on a deployment share for work to mass image new desktops. I am running into this error here and haven't been able to fix it. I supposed it was something to deal with permissions as I can update the share (as a local admin, not on domain) compared to now (logged in as domain user, with local admin rights).
Let me know if there is anything else to try out, I've gone through everything.
=== Making sure the deployment share has the latest x86 tools ===
=== Making sure the deployment share has the latest x64 tools ===
=== Processing LiteTouchPE (x64) boot image ===
Building requested boot image profile.
Determining if any changes have been made in the boot image configuration.
No existing boot image profile found for platform x64 so a new image will be created.
Calculating hashes for requested content.
Changes have been made, boot image will be updated.
Windows PE WIM C:\Windows ADK\Assessment and Deployment Kit\Windows Preinstallation Environment\amd64\en-us\winpe.wim will be used.
Unable to mount the WIM, so the update process cannot continue.
=== Completed processing platform x64 ===
