I am huge fan of MMORPG games, I’ve been playing World of Warcraft for almost 7 years. But the one thing I know for sure is that you have to play those games with your friends and then you will get 100% satisfaction. So, few days ago my friends invited me to play Ragnarök online with them. I downloaded the game and when it updated I started it and got critical error something like mfc90.dll failed to load. When I tried to launch the game for the second time I got error saying that the program can’t start because mfc90.dll is missing from your computer. Few hours I was trying to fix mfc90.dll crash problem until I followed fixing guide posted on Ragnarök forum.
Mfc90.dll is missing or not found error is not related with game, so even if you completely reinstall the game it won’t solve the problem. Mfc90.dll is a system library and if you are having mfc90.dll is missing error it means that the library is damaged or removed. Yes, sometimes it can happen when multiple program access the same library at the same time they can overwrite it and damage. To fix mfc90.dll is missing or failed to load error in Windows you should download and install it from here: http://fix4dll.com/mfc90_dll.
This helped me to fix mfc90.dll is missing error and now I am able to play Ragnarök with my friends. I am sure this fix should work for any game or application that gives mfc90.dll is missing or not found error.
