I definitely haven't seen that.
Do you have multiple versions of Excel installed? Do you get a "run as administrator" dialog when you launch Excel directly (not by opening a file)? That might explain the difference.
Is your cube running on your laptop or another server? (Run as administrator may be in play if it's running locally.)
Can you shut down all Excel windows, then go to Task Manager and make sure no EXCEL.EXE processes are running? Then try opening a particular file and see if you get the errors. (I'm wondering if launching Excel directly opens a new process, and it's not
*how* you open Excel, but it's that you are using a *new* process. Wondering if you can reproduce this after a reboot, too.
When you right click on the Excel shortcut you use to launch Excel directly, choose Properties, then look at the Compatibility tab, are you running Excel with different settings when launched through that shortcut? What about under the Advanced button...
does it say Run as Administrator?
Just brainstorming some ideas that would explain the difference cause I've never seen this.
Thanks for any info you can provide to help me reproduce.
