I have VS2010 up and running for Acad2013 in Windows 7 - works fine. Is there a way that I can compile my ARX projects for Acad2010 using VS2010? I'm having a lot of problems getting VS2008 to work in Windows 7. Unfortunately, I still need to maintain Acad2010 for a few more months.
Installing Daffodil will make it easy to compile using older toolsets. There will be a choice for "v90" in the project configuration page after you install it. You will need to have VS2008 installed though.
