I just installed AutoCAD LT 2008 on another computer, it did fine for a couple of days then I received an error. Application failed to start because side by side configuration is incorrect see event log for further details. This is a "fresh" computer with vista, but since it ran okay a few days, I don't think that is a factor. I am not running another version on it, though I did intall this upgrade without first putting my 2006 on it, but if that was the case, why did it run a few days? How do I access the event log?
