View Full Version : Detecting later versions of an installation

I have created a major upgrade of my app which works well. i.e. it will remove any previous installation successfully, before installing itself.

One problem I have is that if someone first installs the latest version, and then installs an earlier version afterwards, the earlier version does not detect that there is a later version installed so they end up with two instances of the application on their machine.

What is the best way to get round this?

Thanks

Ian
