If you don't have the "Uninstall" directory, then you did an error while installing the product.
And in that case, you should simply do a "rm -rf" from your icn directory.
If you did the correct installation, but still have no Uninstall directory, and you see no errors... then something still went wrong...
Maybe you should open a PMR for such case...
Or have I wrongly understood your problem?
