Please just follow the instructions I posted. If .94 is not showing up then it's not on the PC. Just to be sure you can go to c:\program files\common files\research in motion\shared\ and delete the folder for .94.
Uninstall the Desktop Manager from your computer. This will also remove any OS packages as well.
Install the Desktop Manager back to your computer.
Install whatever OS you want on your device.
Delete the Vendor.xml (again)
Open Desktop Manager and run Application Loader.
