Possibly your best bet is to ask if there is anyone local to you who is willing to help. Preferably, they already have the software installed on there machine and can get you sorted out in the first instance, then continue to persue trying to get it to work on your machines..
I seem to remember that when it worked on my main pc, it recognised the CP2101 to UART driver requirement automatically and then installed drivers automatically. As there were none on the CD. This left only the software to install.
Also, are you installing as administrator? I think if you find the setup.exe file and right click, you should get the option to run as admistrator.
You'll need all AV software dissabled too, not just AVG, so if you have windows shield etc, dissable it.
Incidently, have you read the Losi installation instructions here..
