By default, when you create a macro in Excel and run that macro through a custom ribbon button, that ribbon button macro works only in the workbook that contains it.

To get the same ribbon button macros to work on another computer, you'll need to copy the Personal Macro Workbook to another computer and store it in the XLSTART folder. The link above has all the information you'll need.
Note: Delete the old ribbon button macros. Make sure you create new ribbon button macros that reference the macros from your Personal Macro Workbook.
