I have altered the wupdate in order to update several different versions of my software. This works well with one exception - the wupdate always sees the online version as newer when you check for updates. You can check for updates, download and install. The newer version is installed. Then check again and the message reports there is a newer version available.
I feel as though there is something I'm not updating or there's a checkbox I've forgotten.

Any suggestions?

Thanks
