TWRP not updating

[aaloo]

Hey, i use the Updater app and it boots to TWRP normally.
First it says
Failed to map file '/sdcard/xiaomi.eu etc.zip'
And then error installing file ofcourse.
So how i can transfer the file to /sdcard ?

Just transfert the file normally when your phone is on and plugged to your PC. Then install the file using TWRP. I don't use the Installer in the rom now, as it has encrypt my files and I couldn't access them...so now I just copy the zip when the phone is on and then go to TWRP to install it.
