Even if a domain admin account is used and the "admin$" share is accessible from the Veeam Backup server, the VSS agent still cannot be installed in the guest OS. The following error occurs:
[timestamp] Error Cannot install agent.
[timestamp] Error Cannot upload guest agent's files to the administrative share [\\xx.xx.xxx.x\ADMIN$].

Cause
The %TEMP% or %TMP% folder is not accessible on the server you need to back up.
Solution
To resolve the issue, follow the next steps:
-
Log on to the server with VSS credentials and run the SET command.
-
Find lines like the following ones:
TEMP=C:\DOCUME~1\USER\LOCALS~1\Temp
TMP=C:\DOCUME~1\USER\LOCALS~1\Temp -
Make sure the specified folder exists and that you can perform read/write operations on it.
In addition to user variables, you need to check system variables as well:
-
Open System Properties, go to the Advanced tab.
-
Click the Environment Variables button.
-
Find the System variables section and make sure the TEMP directory name indicated here is valid.
