Icons made for v2.60 in 2010 not working in current version and up-to-date build

[LukeAtreides]

I'm on AIMP v4.60 build 2177 and I can't add these icons: https://www.aimp.ru/?do=catalog&rec_id=80

When trying to, it only lets me add .zip and .aimppack files, and those icons are .rar, but if I try to compress the .dll in a .zip, it says:

Followed packages were not installed, because of invalid file format:

C:\Downloads\valve_aimp.zip

Any fix for this?

Did you tried to install it manually? In 2010, we have no addons manager, so any addons can be installed manually only

Damn, I'm dumb.
Thanks for all you do, Artem!
