If you encounter this error, you could have multiple fix pack entries in C://WINDOWS//.nifregistry. Complete the following steps:

1. Back up C://WINDOWS//.nifregistry.
2. Open the file in a text editor.
3. Remove any incorrect entries; leave only the entries that are actually installed on the system.
4. Try again to uninstall your WAS

Let me know if it worked.

Thanx for yo reply , these are the entries in my .nifregistry file and there are no multiple fix paks entries :

What happens if you try this?

1) Reboot
2) kill all WAS and Java Process
3) Try Uninstall again
