We are trying to upgrade Process Automation from 4.2 SP1 to 4.3 SP1 but the installer stops with below error:
An error Occurred: java.io.EOFException: Unexpected end of ZLIB input stream
Error Log: C:\Users\user\AppData\Local\Temp\Install4Error3868170969606122553.log
<Please see attached file for image>
This error can be seen due to various reasons however following has been identified as the major reason.
Process Automation media being used for the install is either incomplete or got corrupted during extract.
Release: ITPASA99000-4.3-Process Automation-Add On License for-CA Server Automation
Download the Process Automation media again from support site and copy it to the PAM server locally then run the installer.
Note:1. Make sure the user performing the install is added to local administrators group
2. If possible stop anti-virus service until install is complete
