"Protected View" in Excel / Word crash every time.

After november updates in Windows 10 22H2 (I don't know if it's a coincidense or not) we started having several PCs with Office 2016 Pro Plus that show an error every time we try to open a file that activate the protected view (a file from a network path, opened from email or downloaded from the internet).

Instead of show the file content it shows:

  • in Excel, a simple "file damaged", without any other detail
  • in word, an error related to the path lenght, which actually it shows itself even on really short path.

unticking the three box of the protected view obviously solve the issues, but seems not a good idea to me.

I already tried to:

  1. repairing office
  2. do a total uninstall of Office with the official tool and reinstall it.
  3. remove recent updates (one is about the malware definition, KB890830, and can't be removed)
  4. OS check with sfc scannow

but nothing has changed.

can you help me please? thank you in advance.

    Hi @Andr3a_M

    • Could you please check whether Office 2016 installed the recent updates: KB5002521 and KB5002518? If so, please uninstall them for a check. But if not, I also suggest you install them to check this issue.
    • You may navigate to the installation path of Office, such as for 64-bit version of Office 2016, the path is C:\Program Files\Microsoft Office\Office16. Find winword.exe and excel.exe, right click on them > Properties > Details, check their version number.
    • Have you installed any 3rd-party add-ins? I suggest you go to Word and Excel > Click File > Options > Add-ins > Manage COM Add-ins, click Go. Clear the check boxes for any enabled COM add-ins, select OK. Then re-open those files to check this issue.
    • Besides, you said Word and Excel crashes, it's recommended to check Event Viewer > Windows Logs > Applications, find is there is any related record. If yes, please share us with the error modules.
