A workbook I've developed in Excel 2010 for Windows, using VBA code (Userforms, databases, etc), has problems when opened in Excel 2010 on a MAC.
After Macros have been accepted, when one of the Command Modules is selected to open a UserForm, the VBA editor opens up and this Compile Error appears: "Can't find project or library".

It works fine on any Windows system. What is needed to make it work on a MAC?


Thank you.
