Create a folder on your desktop labled HB...
Download Humminbird PC 3.2.0 to that folder..this downloaded file will be something like Humminbird.exe...
Click on this .exe file and it should unpack HB PC into that same HB folder that you created on your desktop...
Once the program is unpacked from the .exe file, there should be 2 items now in the HB folder...the .exe unpack file and the actual HB PC program....
If you don't see the HB PC program in this folder (and only the .exe unpack file) is the only thing listed....on your desktop..go to Start/Programs and see if HB PC is listed there....
If HB PC is listed in your program files...right click and drag it to the HB folder you created on the desktop...when you let go of the right click..choose "Copy File"..
This will make a copy of the HB PC program in that HB folder on your desktop..where you can get to it easily in the future....
Double click on the HB PC program to open in and start studying the "Help" files at the top of the opening page...this is the only manual available for the HB PC program....
I have to log off now but post questions anyway..someone here will help you....
