For whatever reason, some users may not experience controller vibration with their XInput device, even when using official drivers.

There is a custom force-feedback driver that will help restore this functionality.

First, you'll need the force-feedback driver. Here are quick download links (choose only one based on your primary language):

Once you have downloaded the driver, it should be in a .zip package. In order to extract this, you can either use the standard Windows compression utility (right-click it to Extract All), or use a 3rd-party program such as WinZip, WinRAR, and 7-Zip (my personal recommendation). It doesn't matter which program you use to extract this file, as it should extract the same way.

After extraction, you should be left with a .msi file.

Double-click the .msi to start the installation.

You'll be given three choices during the install; Typical, Complete, and Custom.

Typical: Not sure what hardware is supported by this, but this will work fine for standard Xbox 360 controllers.

Complete: This will install the feedback driver for all supported devices (including 3rd-party XInput controllers and racing wheels)

Custom: This will allow you to cherry-pick which drivers to install support for.

Recommendations:

• Use Typical if only dealing with official Xbox 360 controllers.
  
• Use Complete if you plan on using a large variety of controllers, or if you just want to be certain your device is supported.
  
• Use Custom if you know which devices you want support for.

Notes:

• If you want to change supported devices later on down the road, you can easily do this.
  
• The driver isn't huge, and doesn't impact performance in any way. So there isn't a significant difference or downside to using Typical vs Complete, but the option is there.

That should be all there is to it. Force-feedback should now work in supported applications (including DW8:XLCE) with your controller(s).
