How to fix QtCore4.dll is missing error on Windows 10

I couldn’t stand anymore and downloaded and installed Windows 10 64 bit on my computer. I was constantly getting system pop-up messages that Windows 10 is ready, please download it, etc. That was a bit annoying, so I just installed it to get rid of those pop-ups. The installation went smooth. I tried to install it over my existing system to not lose my files, however after the installation I couldn’t run any games that I played on my previous Windows 8 64 bit. Upon launching I was getting QtCore4.dll is missing errors. At first I thought that I need to update some drivers, but even after installing every update I was still getting QtCore4.dll is missing error messages. So, I went to search for the solution on the Internet.


After reading some computer geeks forums I found that QtCore4.dll is missing error is happening because by some reason QtCore4.dll is not present in system folder and a lot of applications including games require it for proper functionality. There are two ways to fix this problem. First one is to reinstall the system and hope that QtCore4.dll will be installed together with system files. Second one, much easier and it worked for me – download and install QtCore4.dll library from here: After that just copy it into the system folder. Detailed installation instruction is provided on the downloading page.

This helped me to fix QtCore4.dll is missing from your computer error on Windows 10 64 bit. It should help you too.
