It does not indicate which file has failed, only
Integrity check failed: file as been tampered with - bad signature"
I've tried to add the file option "Ignore during integrity check", file by file until all are checked but this does not change the results of 64 bit linux. It only makes the working agents (OSX,LINUX_32) to fail when all are checked.
As I said previously, this only happens with 64 bit linux ( haven't tested windows versions or non EC2 64 bit Linux).
