Hi all, I recently helping a friend doing what we are doing. His laptop computer is old enough, some 5 years+ old with 2GB RAM and running Windows XP. First step, I installed the Signalking 999WN and its driver, install OK. Second step, I double click on the VMWare Player 4 installation file, a pop-up window "VMWare Player 4...unable to install in this computer... ", I tried many times but still not working. What's the solution? I need help here. Thanks.
