7-zip unpacking

[Audi1merc2]

I can't unpack the ProMods 2.32 file, I have the latest version of 7-Zip and I tried downloading it on Google Chrome AND Microsoft Edge but it always says that the pack is in an unknown format. As said before I downloaded it several times and the same error still occured.
