Can't install

Hi,

Tried to install Trail version QNX6.3 on Win2k, but the installer couldn’t
complete the installation (Java error).

Now I can’t re-install it, until uninstalling first.
The problem is, I can’t uninstall either (no uninstall info available),
nothing in the control panel (add/remove programs) either.

Removing the files from C:\QNX or the qnx registry entry (in
localmachine\software) doesn’t help either. The installer keeps insisting
now that I already have a ‘previous’ installation, which I can’t remove…

Any help is greatly apreciated.
