PFDCreator Setup - Still geting a "There already exists a printer with the same name." error even af

In my java installer code, I'm invoking the following command to install pdfCreator:

PDFCreator-0_9_9_setup.exe /FORCEINSTALL /LOG /SP /VERYSILENT /NORESTART

The error "There already exists a printer with the same name. Please enter a different printer name" appears during install. I was not expecting this since in my understanding /ForeInstall should have handled that. How do I resolve this? Please advise.

I've experienced the mentioned problem, too!
In my opinion the parameter '/FORCEINSTALL' should handle all issues concerning problems with another PDFCreator installation.
I hope there will be a bugfix very soon - without that function i see no way to deploy my litle programm with PDFCreator automatically. :(
