TIL 2638⚊My Windows computer fails to install a driver when using LabQuest Viewer software with a LabQuest 2 via USB connection.

If the procedure above does not work, for example, if you do not have an internet connection or group policy prevents Windows Update from updating drivers, then download the following files: (Save the files to a USB storage device if you are trying to fix this problem on a computer that doesn’t have an internet connection.)

For 32 bit OSes, download:

(Transfer the USB storage device files to the other computer if necessary.) Unzip the file.

Follow these driver installation steps:

1. Run the Found New Hardware Wizard by following the procedure in TIL 2638 above. Select either option labeled “Yes.” Choose Next.
   Note: You may require Administrator rights for this procedure based on your local configuration.
2. Choose “Install from a list or specific location (Advanced).” Choose Next.
3. Check the box for “Include this location in the search.” Choose Browse. Select the folder containing the unzipped file you downloaded. Choose Next.
