Password for .exe file?

Anyone willing to help a complete noob here? I was directed to the Discord section by the moderator but I can't even find it. Anyway, I just downloaded the newest version of the rpcs3 software and after unzipping & locating the .exe file, I get a window labeled 'encrypted file' which requests a password. Has anyone else dealt with a similar situation?

Thank you very much. 

Use latest version of 7-zip to unpack.
There is no password on rpcs3.net archives.
