Self/Auto Update to latest version - like ClickOnce

[tatva-savan]

Question

I’ve set up an installation using the WiX Toolset and am looking for a solution within WiX that provides functionality similar to ClickOnce. Specifically, I need the application to auto-update or check for updates when it’s launched.

I’ve come across several blogs that explain how WiX can check for and install newer versions during the installation process. However, I’m looking for a solution that performs this update check when the main application is launched, not just during installation.

Open Source Maintenance Fee

• I (or an organization I'm a member of) pay the Open Source Maintenance Fee by sponsoring the wixtoolset project because I support the maintainers.

There's nothing built into MSI or WiX for this. ClickOnce is a per-user installation so elevation isn't a concern. Is your application installed per-user or per-machine?

It's possible to implement auto-update capabilties in your application that interact with the installer. You can solve for elevation also. But mindful of security concerns as you don't want to open an attack vector. For this reason I always have clients implement it themselves with limited guidance. I've thought of creating an open source project for this but I don't want the liability.

Thank you @chrpai for the detailed answer.
Yes, currently setup behavior as per-machine. For this auto-update capabilities (and no elevation), per-user will suites here. But, with the use of per-machine, if it is possible auto-update & also solve elevation problem, could you please provide some reference on it?
