ADME is looking for the short name 'C:/progra~1/avs/etc/scripts/autotapeout.stat' however, the staging server does not have shortnames enabled.

Enable short names on the staging server. If this is not possible, run cmd as administrator. Use MKLINK to make a junction from progra~1 to Program files using the following command:

mklink /J "C:\program~1" "C:\Program Files"

If you make a link, you may also have to look at where the tape backup software is installed and ensure that it is directory is named in 8.3 format or make a junction to it as well.

Verify that the ADME configuration is pointing to the correct paths for these directories in the ADME configuration files.
