Not a good choice for a WIN7 computer. I am using a Gateway netbook, WIN7 Home with a Prolific USB-Serial converter. The program installs with out a problem but freezes up to the extent that the ONLY way to close it is to go the Task Manager. I have also tried it with my E-Machines desktop, WIN7 Home Premium using the same USB-Serial converter with identical results.
The netbook with the USB-Serial converter works, without ANY problems, with all my other TS200 related programs including the ARCP-2000 program.
