i'm assuming this is not an autodesk problem but a Vista problem since i've never had a problem installing autocad before. I was able to install the program but when i try to open the exe file, I get an error that reads "autocad appication has stopped working" the second i click the icon. This also happened with Revit, but when i told Vista to run the program "as administrator" it solved the problem. I was hoping someone here knows how to fix this. i doubt its a 2008 version problem so im posting this in 2008 and 2007. Thank you all ahead of time for giving me any information to help solve this problem and thank you so much for your time!
