How to write a registry entry on uninstallation using wix

Question

Hi,

Is it possible to write to windows registry during uninstallation of an application? Is such functionality supported by Wix. I want to avoid doing it in an assembly and calling the function using custom actions. However, I would not mind creating an in-script custom action.

Regards,

Wamiq

Answer 1

I don't think its even possible on the Windows Installer level, still you can run a reg.exe on uninstall using the quite execute custom action (QTExec) which is build in in Wix.

Answer 2

That's not supported by the Windows Installer. You will need a custom action of some sort. Remember rollback though!
