Dear respected sidscrat,
Good day! Thank you for posting to Microsoft Community. We are happy to help you.
As your description, this problem occurs when the file appears on the list of disabled files for the Microsoft Office program. The program adds a file to this list if the file causes a serious error, such as causing the program to quit unexpectedly. This message allows you to avoid potential problems that may occur if you open the file.
Try to click on File>Options>Add-Ins>under Manage Com Add-ins select Disabled Items in the Manage list then click Go. To re-enable one of the listed items, click the item, and then click Enable.
Also, try to disable add-ins by this way: Open Word>add-ins>Disable add-ins (Clear the check box of the add-ins in the list of COM Add-Ins > click OK and restart application. For reference: disable application add-ins and COM add-ins
If still can’t work, please try torepair an Office application to fix the problem.
Meanwhile, may I know, is that a Word template that you created? also could you please confirm does this error message occur to specific Word file?
Appreciate your patience and understanding and thank you for your time and cooperation.
Sincerely,
Waqas Muhammad
