Sorry I don't have the EUR version. I have a USA WiiU.
After re-downloading the game with utikdownloader again, no error detected by exactfile (SFV checker). Installed wit wupinstaller mod y without problem.
I've also got the exact same error message when I tried to install Breath of The Wind.
Also used utikdownloader.
Then I stumbled upon a SFV checksum file on this forum https://gbatemp.net/threads/botw-install-failed.463167/
It turns out one of my downloaded files (0000001d.app) is corrupt. So...
