Sorry if i am posting on the wrong thread but need urgent help... can you help? I just bought the new macbook pro. I have installed windows vista 32bit with no problems. I tried installing AutoCAD 2008 and 2007 and both give me problems just before then end of the installation. It beings up a small window with the text "MSI...." I have tried it a couple of times and keeps saying this MSI and different numbers next to it. I would close this window and try starting autocad and it just tells me AutoCAD has stopped repsponding... does this mean i need to rather get XP instead of Vista? Will this help at all?
