I already have max 9 and max 2009 32 and 64 bit installed.  I needed to reinstall max2008 for a specific plugin.  After i did so it wouldn’t promt me to put in all the license info for 2008 so i just uninstalled it all.... I think.  Now their is a problem.  I can open all of my max files for max 9, 2008 and 2009 but only if i use max 2009 version.  1st i have to open Max2009 then open the files from inside max.  If i just click on a max file icon on my desktop this is the reponse i get ( look @ pic) —My current system settings are listed at the bottom of this mssg.  Anyone know what i can do to remedy this problem?

Partly this is a windows problem - file associations. You can only associate a file extension (in this case .max) with one application.
Normally, this will be the last version installed (of Max) but not always. I have many versions installed, but if I dbl-clk a .max then I get Max 8, despite them all being installed in sequence.(you would expect to get Max 2010, but no...)

Partly this is a workflow issue. Personally I never double-click Max files, I always load the version I need then File>Open, I also never put “documents” on the desktop, only programs, mainly to keep all the data for a program with the program - that’s for all programs, not just Max

The real problem with using the file associations to load a .max scene (from an earlier version) is that if it opens the latest version and you then save the file it can no longer be opened in the original version, very dangerous.

It may be possible to fix the association problem, but tbh I wouln’t even bother.

Thnx, because i didn’t want to reinstall my XP OS again.  Plus i don’t have a big enough backup drive for all my files.  Thnx bro
