Paragon HDM Pro 15 SP2 / Win10 Pro. 64bit

I am running cyclic backups on numerous partitions to other partitions.

The archives do show up in HDM15 --- however, I am unable to mount them via HDM15. Any ideas out there?

Upon a mounting attempt for a given archive, I receive the following error:

OPERATION FAILED
Failed to open specified plugin
Error Source: Universal Image Mounter
Error Code: 0xe0000025
