[Help - Launcher] File copy error : ./gunz/exe : Access is denied

[vidual]

Title,
my problem is i tried giving permission to it in all the way i could find.
when it wants to copy the file it says this:
16:07039 [ZUpdate] Move patch files.
16:07059 [ZUpdate] Copy patch file from '.\PATCH\Gunz.exe_' to './Gunz.exe'
16:07062 [ZUpdate] ERROR : File copy error : ./Gunz.exe : Access is denied.


16:07062 [ZUpdate] Move patch files successfully complete.
16:07063 [ZUpdate] ERROR : Cannot move patch files.
16:07063 [APP] ERROR - Update fail
16:07063 [APP] Updater error message :

File copy error : ./Gunz.exe : Access is denied.

I have Windows 10 home.
Anyone know the fix?
It also says check for file authorization, no clue how to give it what it needs.
