SAPBPC 7.5 Client uninstall

We're in the process of building a new SAP 10 system to replace our old SAPBPC system.

There are 750 clients that will need the new client installed and this has been packaged, I'd like to know however if someone knows where I can get hold of an uninstall package or a silent script for the existing 7.5 client we're currently using. Any assistance would be very much appreciated

Thanks

Paul
