If you have successfully installed the Dinkey drivers but the LED on the dongle is not lit, or if Setupdrv or the Windows New Hardware Wizard failed during driver installation, the first step is to try a full driver reinstall. This procedure is outlined below:

  1. Remove all dongles.
  2. Go to Start > All Programs > Accessories, right-click Command Prompt and select Run as administrator. Enter an administrator password if prompted.
  3. Using this administrator command prompt, run setupdrv /ufull
  4. Reboot (important!).
  5. Run setupdrv again by right-clicking it and selecting Run as administrator, entering an administrator password if prompted. If setupdrv fails, stop at this point and contact Microcosm or your distributor with the full details of any error messages displayed.
  6. If setupdrv was successful, attach a dongle and allow the operating system to detect the dongle and start the New Hardware Wizard. Select No, not this time if the wizard wants to connect to Windows Update and Search (recommended) or Install the software automatically (recommended) in response to where to find the drivers.

  5. With Everyone selected, check the Allow box for Full Control. Then click Advanced and check both check boxes on the window that opens. Click OK, and select Yes if a "Do you wish to continue?" message is shown. Click OK on the permissions dialog to return to the main registry editor window.
