Usually this kind of problem could be resolved writing a web service that keeps track of the current version of your tool (via an XML file or a database table). This web service provide essentially two methods. GetCurrentVersion and DownloadUpdate, the first one returns to the caller the current version of the tool, the second one returns the binary bytes of your current version.

On the client side, your tool has an option 'Automatically check for updates at startup'. When this option is checked your tools connect to the web service asking for GetCurrentVersion method. If the version returned is newer that the client one, then ask your user if he/she wants to update, start an Updater.exe application and close the tool to be updated. The Updater connects to the WebService, call DownloadUpdate and writes the bytes received over the outdated tool, at the end restart the tool.

  • okay that is queit difficult to understand but do you mean that i have to0 publish my software online ? – A.Wad Oct 29 '12 at 10:24
  • No, if you distribute your tool only on the internal LAN, you need IIS installed to host the webservice but this IIS is not visible to the whole internet. Your clients connect to this IIS using the computer name or IP address. Something like `http://InternalIISServer/tool/updatesvc.svc` – Steve Oct 29 '12 at 10:28
