Made both... place either, or both into this folder:
World of Tanks\Aslains_Custom_mods
And run the installer again, and they'll be installed alongside the rest of your stuff.
Remove-WG-Emblem.zip
Remove-WG-Inscriptions.zip
If you don't want ot rerun the installer, just open the zip files, and place the files into the proper folders.
(Note: Inside the zip, it's called "version" folder, instead of the actual version, due to the installer being able to read that... just so you don't extract the full path, and yeah, you'll get it )
