I was having problems with the autodesk revit software when I was using it. I was constantly getting error messages that would close the window that I was working on and I would also get fatal error messages that would close the program. I reinstalled it and repaired it but the problem was still occurring. I uninstalled the program, downloaded it again from the autodesk website and installed it as I did prior. Everything went fine, I registered the program typed in my serial number and it said that the installation was successful. I then tried to open the program but it wouldn't let me. The start up window appears but nothing happens after that. The program becomes unresponsive. I tried to uninstall it again but it does not let me.
Could you upload the snapshot of the error messages there could be various reasons for this issue to occur? Could you also check the below link and see if this helps out in resolving the issue.
Also have you installed the service pack published by Autodesk? This can be found at the below link.
