cpe file missing

If everything is unsuccessful - even the hard resets - I would contact support.

Did you get any answer from the support? Can you share it with me if it helped ypu?
Because I have exactly the same poblem with my Garmin fenix 6. CPE file missing but when I connect my watch to the laptopp it is there and is updated. Also tried all suggested action above but nothing help me.

Hey Mark, yer they had to replace it in the end. The service center here just did what i did, like reset, factory reset etc. 1 thing i notice the speed of the watch after replaced is much faster...(for saving GPS activities etc). 

Mine had a error file when opening the watch on the laptop, in the error file its a txt file, you can just open it and mine said can not open CPE folder, that is what caused the issue, and can't be fixed...had to be replaced. 

Thanks for answer!
Yes, when I open it on the laptop I also have such error file  with the error message inside where it tells that folder can not be opened. So it looks like I have exactly the same case like you had. So will write to garmin support today.

delete the entire "RemoteSW" folder on the watch.

Reboot watch.

Then sync again with Express.

Already tried to do it. It doesn't help. I tried all advices I found on the forum but it doesn't work in my case

Ok, then you should contact the support.
