@Beckii1317 Try the Method 1 step in this MS tutorial, to make sure that Windows Installer is running. You mention Program files, do you mean you tried to run the redists at C:\Program Files (x86)\Origin Games\The Sims 4\__Installer\vc\vc2013\redist?

1) Disabled UAC
2) Clean Booted
3) Cleared Temp
4) Repaired Game
5) Ran as Admin
None worked.
