Hey. The key for RES3.2 will be a parallel key (unless it has been replaced with a USB type key). There also seems to be some confusion with PCI COMPLIANCE. PCI in credit card processing means "Payment Card Issuer", and PCI in system architecture is Peripheral Component Interconnect. In architecture, PCI and USB are both Serial technologies.
When plugging the licence key in, there is a Rainbow service that picks it up and reads the token's number. Then based on this code, the Micros modules and clients need to be entered in Licmanager. The path should be like:
c:\program files\Rainbow Technologies\Sentinel System Driver\
There is an exe SetupSysDriver.exe , but generally this is executed and ran during the service pack installations.
The licence key does not have to be in place during installation or setup.
On another note, if processing credit card numbers through Micros, PCI compliance for all RES3000 ceases June/July 2010 as the Windows 2000 platform will no longer be compliant.
