Hello Pierre Alain,

Is this issue reproducible? In what scenario? Does the user preview files in File Explorer? Is Excel started programmatically?

The user is getting this error when starting Excel. The add-in has been installed for a while and he's been getting this error for the last 2 weeks, he says.

He is running Office 365. I asked him to do a repair of his installation and reinstall the add-in, but he is still getting that same error.

We have not reproduce this error and this is the only customer having this issue.

Hello Pierre Alain,

Is it possible that they have EXCEL.EXE hanging in processes? Also, please answer my questions above.

The problem has apparently resolved itself.

Great! Thank you for letting me know. If this issue happens again, pay attention to my questions above. I suppose one of them relates to the issue.
