After installing the program on your machine, you need to make a pm85 subdirectory under App\Disk Tools and copy all the files into it. Be sure also to copy prgiso.dll and qtp-mt334.dll from your Windows\system32 folder into the Disk Tools\pm85\Program folder. No registry entries or extra files are needed.
It all works well except the help files which are in html format. I have found that by switching on Enable HTA in Common Components (beta) - common.script, I can get the About box working from within the program. To access the rest of the help files, you need to open Program\Resource\html\help.html from a browser, and everything is then available.
