For the last month or so, my Revit 2013 will not launch. I click on the program and the splashscreen comes up, at which point the program comes up with an error, that a solution could not be found, and that it needs to close.
I also installed AutoCAD 2014 last night, and it worked fine on the first use, but is now experiencing the same issues.
With Revit, I have found that, if I locate a revit file and open it, the program works fine. It seems to just be when launching the program itself that these issues occur.
