Steps to Reproduce



Perform an update to Pega 7.1.7 using the supplied scripts.

Root Cause



The root cause of this problem is defect/misconfiguration in the operating environment. The transfer between the system downloading the media and the system hosting Pega is corrupting the install files. This can be verified by checking MD5 signatures on both sides of the transfer.

Resolution



This issue is resolved through the following local change:

1. Download the installation media and unpackage.

2. Transfer individual elements to host system.
3. Repackage media.
