I recently upgraded to Win11, and have found the following:
2K titles:2K9 May not start and gives a message about side-by-side configuration not correct. See Andrew's post below for the fix to this.
2K10 however worked after it asked to install an older .NET framework.
To me this suggests that there is hope for 2k11 through 2k14 so I will test those out.
Regarding Live titles:So far have been able to successfully reinstall and play
NBA Live 2005NBA Live 2004 works but you will likely require the
updated executable file from the downloads section.
I'm yet to try earlier versions of Live. I had Live 98 and 99 working on my Win10 build, so when I have time I will relocate the resources that enabled those to run on newer systems and see if it works for Win11.
I'll report back with any updates once I get time to try some more older titles.
