Cause

This error might occur for different reasons:

1. When there are several .com.zerog.registry.xml on the file system.
   SiteMinder uses InstallAnywhere and relies on .com.zerog.registry.xml file to keep a record of what product components are installed.
   Only 1 and matching product component .com.zerog.registry.xml file needs to be found by the installer or it may get into a confused state.
   This file usually is found below:
      
      - The user home folder;
      - In the /var folder;
      - In the product installation folder.
   
   ex.:
   
   If "smuser" was used to install the Policy Server originally, this was caused by missing /home/smuser/.com.zerog.registry.xml file.
   
   
2. When the .com.zerog.registry.xml is corrupted or has invalid data.
   
   That could be solved by copying /install_config_info/ca-ps-uninstall/.com.zerog.registry.xml to the home directory of the user executing the install.

 

Resolution

Removing the file .com.zerog.registry.xml under /var solved the issue.
