Environment

SDM 17.3, CA Search Server

Cause

This issue is due to a bug with the InstallAnywhere software version used for the installer, run on a Windows 2019 server with the latest Oracle JDK 1.8.0_281 installed. 

Resolution

1. Open a command prompt and run the following command to set the environment variable for Java:
   SET JAVA_TOOL_OPTIONS="-Dos.name=Windows 7"
   
   
2. In the same command window, move to a directory where the Search Server install execution file is stored.
   
   e.g. C:\Program Files\CA\SC\CASearchServer\_SearchServer_installation
   
   
3.  
4. Perform the installation with an earlier version of the JDK. 
   
   
   
   
5. Uninstall Wizard appears. Proceed the uninstallation.
