To clean up a custom action during rollback, write a rollback custom
action and schedule it at the same time as you schedule the custom
action.

To remove your files at uninstall, just add DeleteFile elements.

There are other ways you could do this but they are more involved.

Subject: [WiX-users] Can I add extra files to delete on rollback in my
owncustom action?

Hi,

I was doing some searching and couldn't find an answer.  In my own
custom action during installation, I've created a couple of new files.
But I notice that after my custom action is executed and if I then
cancel out of the install, rollback don't know about these new files and
they will be left on the computer.  So I'm wondering if there is any way
for me to add extra files for the rollback action (and uninstall) to
delete right in my custom action when the new file is created?
