Retrospect Virtual: Failed to list file during Restore

When doing a restore with Retrospect Virtual, you may see the following error in the Restore Logs:

"Fail to copy from virtual disk. (Fail to list file (The system cannot find the path specified.)" and with the error error "Elevated process does not support to define DOS device".

This error suggest that the logged on user of the windows session where you're doing the restore is not the real administrator and Retrospect could not see the mapped device created for the real administrator session.

It is required to log in as the real Windows administrator and not any other user with admin role or with elevated admin account permission.

The real administrator account will be the one with the security identifier like:

(SID) "S-1-5-21domain-500".

NOTE: For more information about security identifiers in Windows OS, refer to the following article:
https://support.microsoft.com/en-us/help/243330/well-known-security-identifiers-inwindows-operating-systems

You can open a command prompt and run "wmic useraccount get Name,SID" to identify which account is the real administrator.

Please login as a real administrator (NOT the user with admin role or user with elevated admin permission) then start VHS and perform restore or granular restore again.
