How to write a custom action to install a UMDF driver?

Question

I want to install a UMDF software, the only driver from our MSI, I understand that to do it, I need to create a root-enumerated device and then install the driver to driver store. I have never written a custom action before.

Has anyone done it before and can get some code?

Answer 1

Read this topics in the WiX Tutorial:

• Extra Actions
• What's Not in the Book

You may also want to read MSDN documentation on Custom Actions.

Answer 2

It's not recommended to write your own custom action unless you have to because you will have to take care some complex things such as rolling back.

In this case, I would suggest you take a look at the Difx tool shipped with the WDK.
