In the past weeks several of our office computers running Windows 7 64bits and Microsoft Office 365 are randomly displaying the error message "Microsoft sdx helper stopped working". This does not have a severe impact as none of the office applications is closed when this happens, but it is annoying and our ticket tracking system is being flooded by this.
We've tried the following without success:
- Office quick repair
- Office online repair
- Reinstall with another version (x86 -> x64)
- Check for any missing updates for Windows
- Disable Office updates from the File menu
The versions of office installed range from 16.0.12026.20100 to 16.0.12026.20312 and we have computers affected independent of having the office 32bits or 64bits version installed.
I don't know why some of the users are not seeing this message. Maybe they use office applications less often. We've tried to isolate any other variable to understand why it is not happening in every single Windows 7 PC without success.
Any ideas besides upgrading to windows 10?
