QtIFW "Offline" Update



  • Hi,

    I'm using Qt Installer Framework (2.0.1 currently) to produce an installation program for my project. The software works great, and I'm very happy with it. There is one feature I'd like to see implemented, or maybe someone knows of a way to get this result: I'd like it so when running my application installer, if there is already an installation in the selected target directory, the user be prompted to update the software instead of giving an error stating an installation exists.

    Prompting to update the existing installation would be ideal, but if that feature isn't expected in the foreseeable future, then I'd like to automatically uninstall (or prompt to uninstall) the old version, and then proceed with installing the new version in the wizard.

    I realize I can customize my QtIFW installer to detect an existing installation, but it doesn't appear there is a "silent" or non-interactive uninstall flag for the maintenance tool. I looked at the available flags on mine and don't see one -- is there possibly anything undocumented that allows me to run the maintenance tool and uninstall (eg, "./maintenancetool --uninstall")?

    Any other ideas? I realize there is a whole feature for online updates with the maintenance tool and QtIFW, but I'd prefer to package my releases and post the downloads, and have the user manage their updates with the install packages (eg, offline updates).

    Thanks for your time.

    Hi and welcome to devnet,

    For discussing feature of QtIFW, I'd recommend posting your question on the interest mailing list . You'll find there QtIFW's developers/maintainers. This forum is more user oriented. You can also take a look a the bug report system to see if there's anything already fitting your description.
