Support #895
Updated by Daniel Curtis almost 7 years ago
While trying to setup a device I had purchased some time ago, I came across a problem with lack of 64-bit driver support for my device. And now the company that makes this device is out of business, with no hopes of ever creating a 64-bit driver for my gadget. This is a guide on how I modified the existing 32-bit driver for Windows 7 and installed it on a Windows 64-bit system.
*NOTE*: +Abandon all hope+, 32-bit drivers cannot be forced to work on a 64-bit system. Even if you force install them with @pnputil.exe@
h2. Download the 32-bit Driver
The gadget I have does not post its driver online anywhere, so the only place to get it is the installation disc, which luckily came with my gadget.
This document replaces the original file names and data with example data, so adjust accordingly.
First off, I copy the folder containing the driver files named "drivers" (since this gadget has never heard of a setup.exe for installing drivers) to a working folder to tinker with. The file names contained in this folder are:
* gadget32.cat
* Gadget32.dll
* Gadget32.inf
* Gadget32.sys
* libSystemInfo.jnilib
* SystemInfo.dll
h2. Double Down
Once I had the drivers together in a working directory, I make another copy of the drivers folder. This time I rename the 2nd copied folder to "drivers64" and rename the contents of the folder to:
* gadget64.cat
* Gadget64.dll
* Gadget64.inf
* Gadget64.sys
* libSystemInfo.jnilib
* SystemInfo.dll
h2. Analyzing the Donor .INF
Opening up the Gadget64.inf file with notepad.exe reveals:
