Error 1605 - Windows Installer

[Guest]

Hey there,

Whenever I try to execute a windows installer package in any manner, whether
to install, uninstall, modify an installation I get the following error...

Error 1605 - This action is only valid for products that are currently
installed

This happens with any product that uses windows installer

I've tried all manner of things to sort this but to no avail. I've tried
using the Windows Install Cleanup Tool but that doesn't even display the
products im interested in :S. I've also downloaded the latest version of the
windows installer package from Microsoft.

Any help will be greatly appreciated.

Kind Regards

Dann Rees
