Hello!! I bought Studio Hybrid the other day, and I love it, but my AutoCAD won't work on it running VIsta and I need to downgrade to XP. I have a copy of XP Home that I know AutoCAD will work on, and everytime I try to install it, I get the infamous Blue Screen O' Death as it is trying to access the partition information in the setup. I reboot, it goes through the whole process of loading the install files, then tries to read the drive and BAM! BSOD time... If anybody can shed some light on this, I would be greatful. Thanks! I qwould even be happy using this as a dual boot system, but Vista won't let me run the install program, even after I resize the partition to allow it space to install. If anybody knows of a fix for that, I feel it would be the easier solution to the problem as I can run everything else I need in Vista, just need the XP for AutoCAD... Thanks for any help or advice.
