I experienced the sqmapi.dll is missing error when I attempted to launch the update for Windows 10 SP1. I tried fixing the problem by uninstalling it and installing the Windows 10, but the issue persisted. In addition, I cleared registry, erased a lot of hidden files, used different tools, and even removed the license key, but the problem continued even after the set-up of the new key. Fortunately for me, I didn’t bother wasting time to reinstall the entire operating system once again, so I decided to embark on a little research.
The sqmapi.dll is missing error occurred because Windows 10 SP1 update needs to launch the library to function, and when it couldn’t locate it, it sent the error message. I went through my system folder and the sqmapi.dll was nowhere to be found. Am aware that this particular library is a default windows library so it means it was either removed or something happened to it. A lot of things can cause the loss of this library like, virus attack or mistakenly removing it due to high file activity. So, I visited https://fix4dll.com/sqmapi_dll and downloaded the missing sqmapi.dll file manually, after which I followed the website’s installation instructions. In the end of the process I was able to upgrade my Windows 10 to SP1. I hope this guide will be useful for you. Please share it with your friends to help more people.
