Software Deployment

I have create a network deployment for my corporate environment via the instructions provided in the Network Deployment Guide. However, the automated Uninstall of CorelDraw Graphics Suite X4 does not work when I follow the guide.
I am a seasoned application packager and scripter so I have no problems understanding or interpreting the instructions and tailoring it towards my company's needs. Even for the installation, the deployment guide wasn't exactly spot on in detailing how to create Network Deployments, I had to use my experience to fill in the blanks and create a proper automated install. I am wondering if anyone has managed to uninstall X4 with the deployment guide or if they found some other method of uninstalling this product. I am using Novell ZenWorks as the application deployment server backend.

I'm trying to avoid creating my own uninstall of this application, but I know that I can chain 8 MSI uninstall lines with a custom script to remove any remaining registry entries, but that doesn't seem like the right way to approach this since Corel says that their uninstall works.

I've tried:
Setup.exe /x
Setup.exe REMOVE=ALL REMOVEUSERFILES=0 /qr
Setup.exe /x REMOVE=ALL REMOVEUSERFILES=0 /qr
SetupARP.exe /x
SetupARP.exe /arp
SetupARP.exe /x REMOVE=ALL REMOVEUSERFILES=0 /qr

None of these seem to work, the setup.exe's only seem to run a repair and the SetupARP.exe only gives me a windowed option of uninstalling the application, and for a corporate environment we don't want user's to install or uninstall applications, it should be automated through our application deployment server methods. Any help would be much appreciated.
