Oh well, Maybe I should have waited. I was running Isenguard 15.1 on a notebook and upgraded with no problem. I said OK! Lets do the Desktop. I am running 64 bit windows 10 on all machines I downloaded the Zip file and it would not install, and now 15.1 will not run either!
HElp!

Don't take this the wrong way, but "would not install" and "will not run" aren't really very useful statements...

What happened/happens? What were the error messages? What happens when you start 15.2? Have you looked at the log file, or tried creating a debug log (wiki) (perhaps via advancedsettings.xml (wiki))?
