I get an error message that msvcr100.dll was not found

Msvcr100.dll is a part of Visual C + + runtime. If the runtime environment is installed, you can see it under controlsettings installed programs.

The files (VC + + runtime, MFC, etc.) are often part of a package.If it is not available there, you can install the runtime environment directly:
