Windows Could Not Find ...\.MS365CoPilot.Exe

That is the name of the MS365 Copilot Windows app from the MS store. Starting this past month it was renamed in an update from the old name. It appears your version of Office is either still looking for the old version or the new version of Copilot wasn't updated yet.

I would firstly ensure that you are up to date on Windows updates and ensure that your Office apps have been updated. Also go into the MS Store and ensure there are no pending updates. If anything is out of date then it should ideally resolve the issue.

Hi.

My home PC is on standard settings (though I've been thinking of starting to set my own dates for updates as every major W update seem to have some bugs that bricks peoples PC's).

So - For this bug, it's probably OK now if I restart my PC (or maybe update something?) - as in this thread you say it will be fixed eventually. But when I come back from work and sit down in front of my home PC, this issue (today before it is fixed) instantly becomes an error message that I need to research and work out to continue my day. Sure, it might be fixed shortly, but the error message doesn't say anything about whether the problem is known or if/when/might be fixed.That error message should never have been necessary, and the whole thing should never have even become a thing to consider. As long as developers consider what versions people are on, and just include/accept both paths for just a short time until all updates are done. Then eventually, late adopters can be left behind in the end if that is the intended "incentive" for the error message.Hopefully you take this into consideration when releasing patches in the future. So far I believe Windows Update has had enough negative coverage, might be time for some positive.
