It appears that the tool key for the the other manufacturer is embedded into the license key for service tool. I installed an earlier version of service tool so as not to impair the dealer from using their existing service tool with the other manufacturers vehicle. Using the earlier version of service tool I un checked the license in license manager and connected to our control system just fine. Now the question is "How to provide the dealers with one service tool that works with multiple manufacturers under the old licensing for service tool." I do not have access to test any of my thoughts. but simply put.....
Manufacturer "A" has application with tool key embedded into license, it also shows up under the "Options tab in tool key"
Manufacturer "B" does not have a tool key for their application
Manufacturer "A" provided the dealer with the service tool application back when a license was needed for service tool, the license has a tool key embedded
Dealer then purchased a machine from Manufacturer "B" and tried to use the diagnostic file provided with the machine on their existing service tool installation at this point they received the attached message.
