I downloaded the trial and had the product information successfully acquired, but when I actually go to install the program (after saying "I accept" to the terms, and then enterting the information for the product (key and etc)). The installer gets 'stuck' where the overview information is, where you see how much space you have on your computer and how much you need to install 3ds max on it. Apparently, according to my installer, 3ds max is 0 bytes large despite the download being over 3 GB.
Things that haven't worked:
1) Tried opening with admin rights.
2) Turned off any/all anti-virus, as well as firewall software.
3) Run on diagnotics mode.
4) Redownloaded mutiple times and even tried several different accounts to get different product keys.
5) Downloaded the necessary files (such as Microsoft Redistributable C++ 2005)
