Sims 4 Corrupt By Sims 2 Install?

lexilex1020​  Sorry for the late reply.  If you still need help, please post a screenshot of the error message you're seeing when you try to play Sims 4.

Installing Sims 2 shouldn't have had any effect on Sims 4.  However, it's possible that your antivirus flagged something EA App-related once you installed Sims 2 and is now interfering with Sims 4.

For the error code in your other thread, that file is a component of the 2015 and newer VC++ runtimes, which Sims 4 uses.  So please uninstall your current versions and install fresh copies.  Click Windows key-i, select Apps, scroll down to the Microsoft Visual C++ Redistributables, click on any version from 2015 or later, and select Uninstall.  Don't touch the older versions.  You can download the newest runtimes directly from Microsoft:

You'll need both the x86 and x64 versions of the 2015-2022 runtimes, but you can skip the ARM version, which is for a different class of device.  Restart your computer after installing and before trying to play.
