Determining update vs initial installation

[NewsArchive]

Hi there,

I have a customer base of over 150 and I have continual problem with end
users installing updates in the wrong location. My install routine gets
(and puts) the path to/from the registry. Being a Clarion application, my
app is totally portable and it's easier to just copy the app folder than to
reinstall. Sometimes the reg info just isn't there.

In addition to reading and writing to the registry, I'm looking for a way to
determine tell the user that the selected install location represents a
fresh install, then they can back up and get the location right.

So I'm just looking for an approach to this problem. Any thoughts on the
best way to accomplish this?
