I face a firefox problem today. When open the firefox, a error/warning window will pop up. “the procedure entry point _except_handler4_common could not be located in the dynamic link library msvcrt.dll”. It’s really annoying!!! But thank God i found the solution. Here it is :
Go to C:windows/system32/dwmapi.dll
and delete the dwmapi.dll file.
DONE!
i’m apply this method in windows xp. This problem should not happen in Windows vista or windows 7. Thanks.
