Issue:
We un-installed the Siteminder AdminUI via "Uninstall programs " under Programs and Features. However, when we try to uninstall the "Admin UI Prerequisite" , it is giving following error.

"this application has Unexpectedly Quit" Invocation of this Java application has caused an InvocationTargetException. the application will not exit".

How can we uninstall the "Admin UI Prerequisite"?
Environment:
Adminui 12.7 on Windows 2012 R2 
Resolution:
1) Take a complete registry backup of the system to a safe location.

2)Remove the registry of prerequisite 
HKEY_LOCAL_MACHINE\SOFTWARE\CA\Admin_UI_Prerequisite

3) Delete the Adminui install directory and delete the “Zero G Registry” folder.

The Zero G Registry folder should appear as a hidden folder in the same folder as the “CA” folder of the AdminUI install location, by default:

C:\Program Files\Zero G Registry

4) Restart the system
