I can't install Huawei E173 under Windows 7 Ultimate 64-bit Service Pack 1. I get the following message: "Upravljački program nije pronađen" in the screenshot means "Driver not found". I have also tried connecting the modem while connected to the Internet, to no avail. I had previously installed and used 3 other USB mobile broadband modems on the same system, 2 of which were Huawei. All software for these modems is supposed to be uninstalled. However, when I install it under a VMware virtual machine with a fresh install of the same operating system, everything works fine. I have also tried copying all relevant drivers successfully installed under the virtual machine to the physical machine, but that doesn't completely work, either. How can I solve this problem? I will pay $10 via PayPal to anyone who provides the solution.
