After upgrading from Windows 8.1 x32 to Windows 10 x64 I started to have a lot of issues related with missing dll files and other system errors. Usually it happened when I tried to run some program that was previously installed on my old Windows 8.1. The last thing I remember I tried to run some game and the system error popped up saying that mfc100.dll file is missing, please reinstall the application to fix the issue. I’ve tried to reinstall but it didn’t work. Of course it didn’t work, because mfc100.dll is a system file and the error won’t be fixed by reinstallation of the game or application.
I started to read on the Internet more information about mfc100.dll file and what causes mfc100.dll is missing from your computer errors. There are a lot of information about this Microsoft Window’s system library and a lot of factors that can cause that file to become damaged. The easiest way to fix mfc100.dll is missing from your computer error is to download and install mfc100.dll from here: http://fix4dll.com/mfc100_dll.
The installation process is quite simple and well described on the downloading page. Feel free to like and share this guide if it was helpful.
