I contacted tages support regarding how to identify their drivers, and they replied this:
The most reliable way to know the version is the timestamp of the drivers'
signature, atksgt.sys and lirsgt.sys.
I found these files in system32/drivers, but also 2 more similar files matching the pattern *sgt.sys
I tried using protectionID 0.6.4.0 to identify these files, and they are detected as Tages copy protection, but without a version number. The same program can scan .CAB files and will find the TagesSetup.exe that is delivered with the DVD, and in this case it will also often show the version.
Not sure how legit the protectionID thing is, but someone surely put a lot of work into it.
The names of the apparently older drivers that are installed on my system are atjsgt.sys and linsgt.sys.
Hope it helps, this kind of information should be somewhere.
