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.
NBA Live 98 runs successfully as it did on Windows 10, using the steps on the
NBA Live 98 entry on NLSC WikiI will continue to test older titles on Win11 as soon as I can and post more findings here.
