ProjectWise Gateway Service delivers a Product Activation Wizard, but you are not prompted to launch it at the end of your ProjectWise Gateway Service installation because ProjectWise Gateway Service does not require a license. However, if you enable the file caching feature in the ProjectWise Gateway Service's DMSKRNL.CFG file, then you will need to run the Product Activation Wizard on this computer in order to specify a SELECTserver and Site Activation Key for this server to use. This is because you have essentially turned the ProjectWise Gateway Service into a ProjectWise Caching Server, which requires a Right to Run license.
