You really shouldn't be able to access any properties you need in a deferred custom action.  I do something similar in our installer, I lay down a config file, open it up and replace some variables with a custom action.  I use the following immediate custom action to write to the CustomActionData property, then in the deferred custom action, I access that property and use it to read the file.

<CustomAction Id="SetDeferredProp" Property="DeferredCustomActionName" Value="[FILEDIR]" />

Thanks for your quick reply.

I tried setting the customaction to deferred but that also doesn't work. I
don't know how to access files through the CustomActionData property.
I don't have any problems accessing property values either - I can access
the properties I need. I just can't touch any files.

Maybe I can try it a different way - by including the xml file as a binary
inclusion and opening that? Then it is technically not an installed file.
But I can't find a good example of doing that either. Most examples just
execute binary files.

Any more ideas?
