Installation & Licensing

[#1]

What do you mean by "freezing your C:\" drive?

[#2]

its frozen under normal use so that once the computer boots, any changes that are made are destroyed after a restart. 

I use a program called faronics deep freeze. I have uninstalled it for this, unsure if just disableing it was still causing a problem. 

[#3 · Accepted solution]

after talking to some friends who work at Cisco. One by one I went and uninstalled windows security updates as they believed they were the root of all evil involving autodesk. After I uninstalled all the ones I was allowed to, no luck. 

My solution? Well I own a Lenovo and they're awesome. 4 clicks and 1 hour later all my files were backed up, Windows was reset to factory default, files restored, and then I went on to successfully install Autodesk Inventor 2012. Today is a good day. 

Thanks to everyone that read this thread and/or tried to help me solve the problem!
