Hi
Ok, now I know what is that. It appears in project explorer, as well as FUNCRES.XLAM, because they were checked in the addins list.
But the principal issue remains:
I can't manage workbooks because when opening they return an "Automation Error: Unspecified Error" or the error in title.
Now I realize that workbooks that open with no problems can't be saved.
I'm about to believe that is related to the last night Office updates (including service pack 3). - See the attached picture.
Could this be the reason?
If yes, do I uninstall SP3 (Office 2007)?
Any alternative?
