Couldn't start app: Input file application name missing or invalid: RSA key check failed for file
From BOINC Wiki
BOINC couldn't check the encryption key on a file it downloaded. Does the file have a signature?
Solution: Complain about it on the project's forums. BOINC will try to download the file again. Also try to reset the project. It may be that your public key is corrupt. A project reset should fix that.
