A free registry cleaner program may be able to help by removing invalid msvcp71.dll registry entries that might be causing the DLL error. We rarely recommend the use of registry cleaners. We've included the option here as a "last resort" attempt before the destructive step coming up next. Perform a clean installation of Windows. A clean install of Windows will erase everything from the hard drive and install a fresh copy of Windows. If none of the steps above correct the msvcp71.dll error, this should be your next course of action. All the information on your hard drive will be erased during a clean install.
