When we set up a new PC, one of the “highlights” is running through all the years of Revit, currently going back to 2009.
We have discovered that the installations are much happier if we go in chronological order. So, we start with the oldest, and work up one at a time until we get to the most recent version. If we don’t do this, at least one of them will get mad and just won’t run correctly. The splash screen will pop up and then just sit there. Usually it’s 2010. But don’t tell it that I told you.
We have a hunch that there is some wacky Visual C++ thing going on, but we have never found the time to drill down and actually troubleshoot it. The best thing we have is to just go delicately and put them on in order.
