I recently acquired a used Mac with Office 2016 onboard.

When I launch Excel, I get this error msg...

Compile error:

The code in this project must be updated for use on 64-bit systems. Please review and update Declare statements and then mark them with the PtrSafe attribute. OK


As a normal user, I wouldn't think that I'd access to source code, nor would I know how to do what it's asking me to do.

If I just click OK, all spreadsheets open as they should. So, this is simply an annoyance factor, unless I'm missing something. But ideally I'd like the message to go away.

Suggestions?
