Launch Conditions have to be true in order for the install to proceed.
Therefore, if you had:
<Condition Message="Such and such file does not exist. Aborting
installation.">FILEEXISTS</Condition>

OK well it might need to check part of the way through the installation,
not quite sure yet. How do you stop it from proceeding if the condition is
not met? That's the part I'm interested in…

If this file needs to exist before the installation is ran, you could have
something like:
<Property Id="FILEEXISTS">
<FileSearch/>
</Property>
And if the FileSearch succeeds, FILEEXISTS would be set to true. Then you
could have a <Condition/> that won't let the install proceed if it isn't
set? I've done this with a <RegistrySearch/> before.

I would like to use the FileSearch property to trigger a rollback if a
particular file is not located. I know how to use the FileSearch property,
but not hot to force a rollback based on its outcome. Can anyone help me
with this one, or point me in the right direction?
Thanks
