How To Fix Sims 4 Will Not Launch In Windows 10 Issue

Sims 4 is a very popular life simulation video game originally released in 2014. In this game, the player controls a simulator and controls different aspects of his life. Although it is a reliable game, sometimes you may encounter certain problems. In this latest installment of our troubleshooting series, we look at the issue of The Sims 4 not opening in Window 10.

What to do if Sims 4 doesn’t run on Windows 10

Before performing any of the troubleshooting steps recommended below, it is best to completely restart the computer. This action refreshes the operating system and removes any temporary corrupted data that may be causing the problem.

Several factors can cause this particular problem, from a corrupted game file to a problem with the graphics driver. Below are the recommended troubleshooting steps to follow to resolve this issue.

Remove accident reports from the Sims 4 folder

The first thing to do in this case is to delete two files, lastCrash.txt and lastException.txt . Lastexception.txt files are created when an error occurs in the game code.
