How can I reinstall Port on XP since I get the unsigned driver dialog which interrupts installation, requiring a manual mouse click to continue?
To specify a policy that allows unsigned drivers to be installed, use one of the following: Implement a driver signing policy by using Group Policy. Under Administrator Tools, in the Active Directory Users and Computers snap-in, right-click the domain root, click Properties, and then click the Group Policy tab. Click the default domain policy, and then click Edit. Expand Computer Configuration, expand Windows Settings, and then expand Security Settings. Expand Local Policies, expand Security Options, and then modify the ‘Device’ setting: Unsigned driver installation Behavior to the setting that you want to use. Note This policy is a domain-wide policy, but will allow to you to install the Port keyboard driver. (this driver cannot be signed because it does not support an actual hardware device).
