I'm running into an interesting problem... when I try to use the installer locally on my machine, it runs fine. When I try to run it from a CD that I make, it gives me a dialog with "This archive has an unsupported version." error...
In order to figure out the source of your problem please give us more details.
When you are trying to install the package from the CD, the target computer is the one on which you created the package, or another?
Also please send us the error code.
