Error 20003 failed to configure vCenter Single Sign On

During installation of vCenter Single Sign On 5.1 the following error message appeared:

“Error 20003. Could not configure vCenter Single Sign-On”

error_20003_vCenter_SingleSignOn

The solution in our case was VMware KB 2046318.

Cause:

This issue occurs if a third party application installed on vCenter Server uses Java.

Resolution:

We removed the JAVA_HOME environment variable:

Java_Home_vCenterSingleSignOn

Then we started the installation wizzard again and the setup finished without any problems.
