I've reinstalled ie7, ie8, ie9; none will load even if the installation goes as far as asking to restart the pc. Generally, I use firefox. But there is an application that requires IE. The IE add-on doesn't help. [similarly for Chrome] Anti-virus is turned off and neither the 32 bit or 64 bit versions load. Hotfix did not help. Tried to fix registry manually and ran into: Mshtml.dll was loaded, but the DllRegisterServer entry point was not found. Subsequently, ran into cmdin.dll not found.
