I have an excel addin loaded on multiple machines (all pointing to the same xlam file on a server), all but one can run macros from the ribbon buttons. The one machine that cannot, the macros can run if I call them from inside the VBA editor (which upon opening shows the addin in the tree view). So I know it is not a security settings issue an addin unloaded issue, not a syntax issue because everyone else runs the macros from the same ribbon buttons without issues. The ribbon buttons were created using the customize ribbon within Excel, not coded manually. I have unloaded and reloaded the addin to no avail. The machine in question ran these macros from the ribbon without issue for over a year and now mysteriously spits out the message:
"cannot run the macro the macro may not be available in this workbook or all macros may be disabled"
Any clues to what could make the ribbon unable to call a macro on a single machine, when it is able to run if called from the vba editor?
