Cannot validate exe

I’ve just downloaded gitea-1.7-windows-4.0-amd64.exe and gitea-1.7-windows-4.0-amd64.exe.asc, and I’m trying to validate it with gpg, and I get

gpg --verify gitea-1.7-windows-4.0-amd64.exe.asc gitea-1.7-windows-4.0-amd64.exe
gpg: Signature made Sat, Feb  9, 2019 12:19:50 PM AST
gpg:                using RSA key CC64B1DB67ABBEECAB24B6455FC346329753F4B0
gpg: Can't check signature: No public key

I’m running it from a windows 10 home edition, using Cmder, wich provides some bash unis utilities.

Any idea?

Did you import the key from keyservers?
