Do not enable all macros! That is not needed to enable macros.
Instead, disable all macros with notification.
Make sure the templates containing the macros are in a Trusted Location.
When in Word, what happens if you press Alt+F11 (+Fn on some computers)?
It should open the vba editor. Look at your Normal project. Does it have any modules like NewMacros?
Are these document templates or global templates?
Some very old templates are not accessible.
I have the old Pleading Wizard and Calendar Wizard from Word 2003 and they simply will not run no matter what. The vba is stripped from them when they are used.
