[Closed] Get all 3ds max installed versions

Hi guys

In a C# software, I’m trying to find a way to detect all 3ds max versions installed on a computer and until now I was using the environment variables (like : ADSK_3DSMAX_x64_2016), but I’ve notice that 3ds max 2010 didn’t add environment variables…
So how would you find all installed 3ds max ?

BTW, could someone help me find old 3ds max version, like 2009 / 2008 or even older ?

Thanks for any help
