Nope, Snapshot is fine,

1. You need winrar from https://www.win-rar.com to open it.

2. If you downloaded the 700MB files , you have them all in the same directory and open the one with the extension part1.rar
Then open ZeitcoinBlockChainSnapShot-2017-12-19.rar and follow the instructions from the https://www.cryptopia.co.nz/Forum/Thread/1336?postId=7831

Verify the checksum matches for ZeitcoinBlockChainSnapShot-2017-12-19.rar and if it does the file is not corrupt.

Screenshot of the error you are getting if you want help installing it.
