Can not find Nordic dongle from my application

I have an application that do SW download to STM32L151 processor using NordicDongle with MasterEmulator.dll (Version image description It works good on my desktop windows 10 computer. When I am installing the application on a windows 10 tablet it does not find the Nordic dongle I installed the dongle driver and see it on the com port list in the device manager as "JLink CDC UART Port (COM 19)" I use master.EnumerateUsb(); to locate it but does not get anything. I do not have Visual studio installed on the table so it is hard to debug it and the same application as I mentioned works good on my desktop. Thangs Ofer
