How to solve the error message: "Office has detected a problem with this file" or "Excel cannot open the file..."

Published: October 26, 2016 (latest revision June 29, 2023)
reference id: QA0297

We've only got this reported a few times and cannot reproduce this ourselves, but we still want to address it here:


A few users reported that after they installed ASAP Utilities 7 on their system with Excel 2010, they get the following error message when they start Excel "Office has detected a problem with this file" and then ASAP Utilities doesn't start.

In Q4 of 2021 we got this reported from a few users with Excel 365 too. Suddenly they received the error "Excel cannot open the file 'ASAP Utilities.xlam' because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file." But the file is still correct and hasn't changed.

** update 2 **
Based on the contact with a client in November 2021 we found that this my be caused by one or more rules in Windows Defender too.
If you use Windows Defender, then please read the following:
