only prompt for directory on new install?

[glenncarr]

Is it possible to show the details screen (and specifically the install directory) in certain situations?

A registry entry is made on the first install, and subsequent installs check to see if it is there to determine if it is an upgrade.

We'd like to be able to only prompt for the directory on a new install, and not prompt for a directory on an 'upgrade' (i.e., they are installing over an existing installation).

I'd like to be able to set the "InstallSilent" to "silent" if the registry key exists, or "normal" if the registry key doesn't exist.

Any ideas?

Thanks,
Glenn
