Based on the testing done by our engineer, the GPSInfo file uploaded in our website works well with the Windows Mobile 6.1 cell phone. As stated, the GPSInfo program is an executable file, not an installation file.
Please copy the GPSInfo and the Microsoft ActiveSync program into an SD Card and insert it into your HTC mobile. Run both programs to install them. If this steps doesn't work, perhaps HTC & Verizon lock other GPS software and that is out of our hands.
