On an up-to-date, Intel-based Mac Book Pro, my client installed Mac Office 2011 along side Mac Office 2008. Client states that they stopped an Update from Microsoft for Mac Office 2008 before it completed and since then Excel 2011 won't start. Excel 2008 starts fine. Other Office 2011 apps start fine. Launching Excel 2011 causes the following error message:
"Microsoft Excel cannot be opened because of a problem." Check with your developer to make sure Microsoft Excel works with this version of Mac OS X....."
Things I have tried:
1. moved the "pref" files for Excel 2011 as a temp workaround
2. installed the latest updates to Mac Office 2008
3. Reinstalled Office 2011 and updated with latest update.
4. Repaired Permissions on the disk drive and rebooted.
The problem still remains.
Any ideas? Thanks in advance.
