Compile Error in Module 1

If you see this "Compile error in hidden module: Module 1" message:

:

more likely than not you have installed the 64-bit version of Office. Pathagoras (and many other add-ins) cannot run in Office/Word 64-bit.

32 bit is the preferred installation of Office. We recommend that you uninstall Office (64 bit) and reinstall Office using the default (32 bit) settings.

NOTE: Pathagoras runs just fine in a 64 bit operating system (e.g., Windows 7, 64 bit. Be sure to distinguish between the operating system and the program.)
