[Nant-users] msi and conditional component installation

[Ted Quinby]

I'm trying to conditionally install a component on the target machine -- depending if a file previously exists on the target machine.

What is the best way to implement this?

I see there is a condition parameter in the <component> element of the msi task.  This seems like the most logical place.  However, I can't seem to figure out how to evaluate whether a file exists on the target machine at runtime.  It seems like the <search> element of the msi task might be able to achieve this but the documentation suggests this is registry specific.  The documentation actually states that the search element can search for a file or directory but the required 'root' parameter confuses me and leads me to believe that it only searches registry values.

Thanks in advance!
