XLS Padlock: Add-in 1 System Error. Code: 59

Hi crew! Have a user that is not able to open the program and cited Add-in 1 System Error. Code: 59, An unexpected network error occurred.

Wanted to ask if anyone has seen this yet, thanks.

Is your user running Windows 11 Insider Preview? Is he running Excel 64-bit?

Any news on this error? One of my user has the same problem

Same questions before we can help you for this issue.

Windows 11 versione 24H2, Microsoft 365 vers. 2408.

A new build for the Windows 11 24H2 update released by Microsoft broke something in our virtualization engine. We contacted our provider and they are working on a fix.

Any news on this? Thank you

Yes, we’ll have an update available in a few days.
If you agree, we can send you a preview for you to test (it’s not a Beta, it’s a final build being tested before release).

Yes, sure I can test it.
Let me know.
Thank you.

Final version was released yesterday. Please upgrade if you haven’t already done it.
