CAUSE

The report will fail due to Excel security.

RESOLUTION

Permission for DCOMs "Microsoft Excel Application" are causing issues. Here are the instructions to follow in order to resolve the issue;

1. Go to Start>Administrative Tools>Component Services>Expand computers>My computer>DCOM Config.
2. Find Microsoft Excel Application and Right Click and go to Properties.
3. Under security set all to customize and then edit each one to add the user you are currently logged into with full access.
4. Launch Excel to test that the error "cannot use object linking and embedding" is gone.
   Note: Excel may re-configure out of box again and click ok to confirm user and initials.
5. Once you can launch Excel without config on startup and error, your reports should no longer fail.
