I did a system restore today in the morning, because I encountered a problem with my firefox. Being the restore point yesterday and after that I have been getting the following message, which is kind of cryptic:
"the procedure entry point ?readWriteLock@QObjectPrivate@@SAPAVQReadWriteLock@@XZ could not be located in the dynamic link library QtCore4.dll"
I have been playing yesterday Diablo 3, so I do not think that the system restore is the problem.
So I uninstalled the game and tried to installed it again, but when trying to run the installer the same message pops up.
I have attached a picture of the Error. Hopefully someone will know what is going on. :(

I can play any other game like Starcraft 2, the Witcher 2, Dawn of War II, etc.
