Where can I download the 64 bit version of the LaunchU3.exefile?
I have a xinwei wireless modem to install on my windows 7 64bit computer. The install cd returned an error, asking me to install the 64 bit version of the LaunchU3.exeon my computer first.

I can't find a 64 bit driver - evidently they haven't written one. (That's one reason to stick with name brands, even if they cost more. Your adapter cost you infinite dollars per usable byte, since you won't be able to use it.)
