Fix #6: Reinstall the program

If the msvcp100.dll error appears whenever you run a certain program, then try to reinstall that program. It is likely that the application is at fault.

Fix #7: Perform a clean Windows installation

You can also try to do a clean installation of Windows to delete any problematic DLL files and install new, and hopefully, error-free files.

Fix #8: Get rid of system junk

Often times, unnecessary files mess with your system causing errors to surface. Use a PC repair tool to get rid of these unwanted files and optimize your machine for top performance.
