0riginalBambi Right, I'm saying don't use the installer in the game's program files; uninstall your current version and reinstall using the Microsoft download, then see whether the game installs correctly. It's possible the EA App will detect the runtime already present and skip that step.
Sims Medieval's installer hasn't been updated in a very long time, certainly longer ago than the newest update for the 2005 runtime, so it's not a surprise that Medieval's copy of the runtime installer wouldn't be compatible with a newer system.
And it's also worth removing all your 2015 and newer VC++ runtimes and replacing them with the x86 and x64 2022 versions, just in case the App is tripping over that and not the 2005 version.
