I can't install xiaomi.eu for my mi5s. When I try to install I get error

Updater process ended with ERROR: 7
Error installing zip file '/sdcard/xiaomi.eu_multi_MI5S_V8.5.2.0.MAGCNED_v8-6.0.zip'

md5 for this file is ok

Are you using Updater app?
You should not!
Use TWRP.
BTW, your device is unlocked, isn't it?
