I'm not sure if this would be the right board to post this in, I figure any Revit board is better than nothing. So for some explanation, I am a student using the educational versions of Revit AutoCAD and Inventor. I recently switched to a new hard drive on my PC and re installed all of my programs. I had no problems installing the other software, but when I go to install Revit I am greeted with an error that says "Another version of this product is already installed. To install this version, you need to remove the existing version of this product." I have sifted through all three drives on my PC and the only instance of Revit anywhere to be found is the installer that is giving me the error message. I have no idea why it would be saying that, I'm hoping someone else either had the same issue and can shed some light on how to resolve this. Thank you in advance!

Please mention Revit version, especially when uploading Revit files.

I'd also use the Microsoft Fix It tool
