eXport projects dont debug in MicroVision - No debug device found

Exporting simple code for flashing an LED to Microvision worked in the past, if the Debugger settings contained a serial number as shown below:

however if we exported the same programme on a different PC we would get the following blank Serial number fields

in which case the error messages were:

we can now predict working projects from non working based on the presence of the serial number, but we have no idea why ?

the exported projects compiles under Microvision -Build all - with, no errors no warnings.

I'm not sure where to look,

NOTE: THE SAME MBED BOARD, WORKS ON ANOTHER PC WITHOUT A HITCH. the board is updated .

ANY HELP APPRECIATED.

:-) hAIKO

to sum up: is there some kind of driver that is required to run on Win7 to make the Keil debugger work ? the above with the Serial Number filled in works, when serial number is not filled in, does not work.
