I tried following either step 1 or 2 and get a strange error, "The file can not be accessed by the system."
Kodi was working fine before the update. I checked file permissions and they're all OK. I google the error and find unrelated stuff to do with servers.
I used command line and unstoppable copier. I rebooted. I did a chkdsk, nothing lets me copy all the files from this folder. I get about 3400 out of 7000 files when using a copier program. Windows explorer copy simply aborts the copy immediately.
Does the store lock down app folders for security or something?

If I can I will switch away from the store version and back to the regular one.

I just tried Solution 1 and ran into exact same issue as you.

-> copied Kodi folder; pasted into AppData\Roaming
-> tried to copy over 8,000+ files
-> immediately comes up with error message:
 

An unexpected error is keeping you from coping the file. If you continue to receive this error, you can use the error code to search for help with this problem.

Error 0x80070780: The file cannot be accessed by the system.

Seems like this is a common error in this thread. Has anybody found a solution yet? Or have an idea of something else to try??
