I am running windows 8.1 (i think) 64bit and I get that error message on my system. Any suggestions on where to look next. Is there a list of prerequisites. I have the new ASCOM platform. System is up to date for the most part. Not sure where is am having issues.

Pretty sure the above info doesnt matter but I wanted to pass it along just in case.
