For security reasons, make sure your Microsoft Office software is set to disable macros. The setting we recommend will disable macros, but warn you so you are aware. When you see the warning, you can enable macros on a case-by-case basis (only if you expect them to be present and you are absoluately certain they are legitimate!)

These instructions work for most versions. If your version is different, search the Help in the program for Macros.
