USB 3G modem

I am trying to install a huwai USB 3 G modem internet stick. (Australia Vodafone)
It went into a laptop with vista x86 ok and into a pc with win 7 x64 ok.
I treid in into another pc with win 7 x 64 and almost at the end of instalination i get this error 1935.
I did a search on it and came up with error 1935 during office installs, i cant find anything on a usb modem install error.
Attached is a pic of the error message

If possible, uninstall it, then start over. If it won't uninstall, or if it won't reinstall afterwards, try using System Restore to roll back to a point bore you started the installation, then try again.

I have done all that.I had an hour on the phone with vodafone tech support and they directed me to download updated software. Which i did with the same error at the end.
