Hi, I am spanish, so I'll tryto explainas best I can. I use win 7
First I install 3DS Max, (trial version) it works perfectly. Then I unistall VRAY using Revo Unistaller Pro, but this programeliminated severalfiles in the folderof3DSmax, and it stops working, so i unistall completely 3ds max and reinstall, but when i try reinstall, the installer says to me that 3DS max is already installed. After that, i try to unistall all autodesk software in my computer, (autocad, librarys... etc) and reinstall them, all work perfectly, except 3DS max, when i try to reinstall, the installer says me that 3DS max is already installed.
