## Symptoms

- * Endpoint Security on Demand (ESOD) fails to start the scan with error "Check Point Deployment Shell Internal Error" or "Internal Error Code 50"
* MD5 checksum of the *ics.jar* on the client is different than the MD5 checksum of the *ics.jar* on the Security Gateway.
* Deleting the *ics.jar* on the client, and retrying the ESOD, results in a new *ics.jar* downloaded with the wrong MD5 checksum.
* On the chsell.elg file we see the following:   
  INFORMATION \[global\] (Log log) \[CShellPackage\] You have 64 bit java runtime, which requires ics with the same architecture. Current GW doesn't contain 64 bit ics. **Please, update you ICS component to the latest.**

## Cause

The *ics.jar* file on the Security Gateway is corrupted.
