Cannot uninstall own test installation following InstallAware trial

[MartinBUK]

I installed a trial version of InstallAware Admin Studio and used it to create a test installation of my software.
I subsequently decided to purchase the Developer version of InstallAware.
However, this will not uninstall my test installationfrom the Windows Control Panel and says I need to licence InstallAware (which I have - the Developer version).
I am now stuck with my test installation on my WIndows machine. How do I get rid of it?
Thanks for any help.

I have managed to solve this problem by using the Revo Uninstaller program to force the uninstall; so no longer a problem.

I shouldn't have had to have done that though. Something for InstallAware to look at I think.
