When I open the browser, I receive The procedure entry point_except_handler4_common could not be located in the dynamic link library msvcrt.dll message. What can I do?

If the problem appears after installing or upgrading the Mozilla
Firefox browser to version 3.5 (or later) operating under Windows XP,
the problem is due to a Windows Vista driver (dwmapi.dll) installed in
a Windows XP OS at folder system32 by mistake (faulty install
program). Delete that dwmapi.dll file to fix the problem.

This error is caused by a 3rd party utility or applcation overwriting your msvcrt.dll with a different version.

For example if a windows vista version of this DLL was copied on to a windows XP computer you would probably get this error.

In order to fix the issue, I suggest you upgrade the browser to the latest version. Also, you can find and download the msvcrt.dll file in (C:) > Windows > System32 folder using Google search engine. Another solution is to run the Dll-Files Fixer which is developed to solve all .dll related issues.

I found this answer. Just go to (If you're using windows XP) "C:WindowsSystem32" directory and delete DWMAPI.DLL if it's there. This file belongs to windows vista and shouldn't be on Windows XP.
