Microsoft Office 2011 for Mac - Excel Error Exception: EXC_BAD_INSTRUCTION

Question

Hello -

I have read several online posts in this community on how to fix similar errors on a Mac, but all the ones I have tried have failed so far.

CURRENT ISSUE: I cannot save any Excel files without it crashing. It seems like save is the trigger for MS Excel to crash and it does without fail. 

Here is the error that appears after Excel crashes: 

Microsoft Error Reporting log version: 2.0

Error Signature:

Exception: EXC_BAD_INSTRUCTION

Date/Time: 2015-04-26 01:40:08 +0000

Blame Module Offset: 0x00237074

Application LCID: 1033

Extra app info: Reg=en Loc=0x0409

Crashed thread: 0

I have done the following already without success in resolving the above: 

Reinstalled Office 2011

Verified the account information for MS Office is correct

Checked and corrected font issues in the Font Book 

Removed plist preferences for Excel

Saving in different file formats  - even trying to save templates found in Excel. 

Side note: OS on my Mac is up to date with the latest release and I dowloaded the updates for Office 2011 that came out this month.  

My Macbook is only 5 months old and I have had Office 2011 on my laptop for almost all the time I have had it. The issue is new as of today. 

Thanks.

1. Repair Permissions using Disk Utility

Run two or three times to make sure all repairs are done

If you see the same identical item appear again. Most likley you have false positive

(there has never been a time where Disk Utility didn't show at least one or two false positives, they can be safely ignored.) 2. Next Open Font book

a) in left-hand window pane select All Fonts

b) In right-hand window pane choose first one font, the hold down option key and ⌘ - A

     (Select all) 3. Next select from File menu Validate Fonts. 4. When Validate Fonts window open click its titlebar and switch to error and warning only. 5. If any show up, remove all shown as defective/Damaged immediately remove. 6. If errors show up about duplicate fonts locate and remove duplicates keeping l the newest versions

Remove duplicate and empty Trash*. 7. Now select all Fonts again and repeat validation of fonts until you get a clean bill of health.

* go to this Website 

Follow directions given in section about FontBook and Lion on up. You can follow directions on how to make a back up of good fonts that have been removed. (in case you need to swap fonts.
