[Q] Updater plugin?

G'Day,

I would like to have some form if installer that will download files from a remote site and run the NSIS installer to update the local files. Basically an application update.

Now the features say it can be done :-) and there are some threads that talk about it (Web Updater ) but I cant find a working solution.

Has anyone got any pointers?

TIA

1) Use a plugin to download a settings file containing the current version of the software, etc
2) Check which version is greater
3) Download if necessary
