I have this Cricket ZTE AC3781 usb modem and it won’t install on our main windows PC. I even updated it from Vista to Windows 7 a few days ago and the same problem occurs. I plug the device into the computer, and the cricket software installs without a problem (The actual program with the connect button so you can get online).
However, after that stage finishes, the computer attempts to install the device drivers, and this is where the error occurs. I have no clue what to do. It just hangs on “Data Interface Searching Preconfigured folders for drivers”. I had an old Linux Mint machine in my room. I wiped the hdd & did a clean Windows 7 install on it, and the modem installed flawlessly.
Why does it work on this computer and not the other? If it helps, this is the 3rd modem we’ve had. The 1st one caught a shortage so we got it replaced. the 2nd one is when the problems started to occur.The drivers wouldn’t install and would mess up my computer to the point where I had to do a system restore after every failed installation. I never got it to work. This ZTE modem is the 3rd one.
Any help would be great. I mean even if I fiddle around in Device Manager, the computer will hang when I choose to unistall the “Data Interface” drivers that have the exclamation mark beside them. I have to hold the power button and reboot or the unistall bar will go on forever or the computer will crash and need to be restarted after it goes to sleep.
