Fixing the QtCore4.dll not found in Sims 3.

Today I’ve decided to play Sims 3 before starting Sims 4, so I found a CD and installed the game. After the installation was completed I launched the game and the error popped up saying that the program could not be started because QtCore4.dll is missing, please reinstall the program. Well, since I am not expert in computers I just reinstalled the game and wasted another hour, but it didn’t help. Every time I try to start the game the QtCore4.dll not found error appears. I started to read Sims forums and found that a lot of people having the same problem. However, I was lucky enough to find a great guide about how to fix this problem and I am about to share it with you.


The fix for this problem is easier than I thought and even with my miserable computer knowledge I was able to make my Sims 3 working. So, I found that QtCore4.dll is a part of Electronic Arts Download Manager and the problem is not in Sims 3 game, so that’s why reinstalling the game can’t help at all.

To fix the QtCore4.dll is missing error in Sims 3 you need to download QtCore4.dll here:

Now, when you have QtCore4.dll file, just place it into the C:\Program Files\Electronic Arts\EADM folder. Everything should be working now. Enjoy the game and don’t forget to share this guide with your friends!

If you have d3dx9_31.dll is missing error you can find the fix on this article.
