Network licensing error

Hi all,

I downloaded maxplus II executable:baseline10_2.exe into a PC with windows vista and installed.

But, I am getting the following error while installing: "Network Licensing error: the software guard cannot be read. Make sure that software guard and sentinel driver have been installed correctly and that the sentinel driver has been configured correctly"

The same license file works in windows NT machine. But, I downloaded the executable and installed in windows vista PC and I set the the license set up. I am getting this error. What will I need to do to get around this problem.

Thanks for any words of wisdom.
