On a computer running w10 with office 365 suddenly the file association of office was lost, I have fixed it except for the .doc files, if I double click a file it will open Word but a message will show up saying that Word isn't the default application for those kind of files

I have tried uninstalling and reinstalling office with no success. Also the file association in the control panel is correctly showing Word as the default program for doc files

Any ideas on what can be happening?

I had a similar problem, and the fix for me was to right click and select "open with another app". Word wasn't listed so I had to select "more apps". Then when I found Word there was a little checkbox titled "make this the default app for opening .doc"(or something like that). This seems to have fixed it for me.
