Max files open with the wrong version of Max, and Open-With doesnât fix it
In Windows Vista, the âopen withâŚâ command doesnât like to differentiate between programs that have the same filename, even if they are in different folders. This means that if your .max files are opening with max8t and you want them to open with max2009 32 bit, trying to do âopen withâ and navigating to the folder with the correct version has no effect.
This can be alleviated by a simple registry edit. Youâll probably need to log in as an administrator. Just run regedit.exe and navigate to:
HKEY_CLASSES_ROOT\3dsmax\Shell\Open\Command
Rightclick and modify the entry on the right showing the incorrect directory to run max from, and change it to the correct one, following the existing syntax. In my case, Iâd type:
âC:\Program Files (x86)\Autodesk\3ds Max 2009\3dsmax.exeâ â%1â
After that, you can change the text it shows at the top when rightclicking on a max file by going up a level in regedit to:
HKEY_CLASSES_ROOT\3dsmax\Shell\Open
and change the value that shows up on the right to have the proper text. In my case, Iâd use the text:
Open with Autodesk 3ds Max 2009 32-bit
If you havenât used regedit before â donât change or delete anything unless youâve verified elsewhere that it isnât going to break anything. if you donât know what youâre doing, find someone who does to help you. Same reason you wouldnât delete your âwindowsâ folder.
