Hi All,

I have deployed a package to particular AD Site Windows 7 Clients which will receive the program from same DP to all systems.

19 systems are failed with downloading the package. 115 systems are successfully completed the program installation. I checked the cas.log for the download failed systems. All the systems failed with hash code mismatch.  I have cleared the CCM cache file and it did not help to solve the problem. 

Please help me to solve the problem.

Regards,

Boopathi S

It can be caused by your Anti-Virus solution.

I've also seen issues with hidden files :
