    The Windows installation package registers a command line for uninstalling the package. Running this command line does not uninstall the package.

    The command line ends with "/modify". For uninstallation, it should be "/passive /uninstall".

    Windows provides for separate command lines for modifying and uninstalling packages to be set in the "Uninstall" subkey:

    • ModifyPath: Command line for modifying the package
    • UninstallString: Command line for removing the package

    By setting both keys, the ARP control panel will display separate buttons for the two operations.

    Having an uninstallation command line that does not do what it says, and in fact causes modal UI to be presented, also interferes with automated package management.

    Ceterum censeo: This bug would have been avoided by using MSI as the distribution package format, because "msiexec /qn /x [ProductCode]" would have been correct regardless of what the registry says, and even if the registry does not say anything because the Uninstall key (as well as the uninstaller executable itself) were actually deleted months ago as part of some expired user profile. See bug bpo-25166.

    I'll take a look at having separate commands set, but the component responsible is external and this may be an issue for them.

    Also, for future reference, continuing to point out that you would have preferred an MSI does not help you get faster assistance, and does not count as more "votes" towards any change. Continuing to add it will eventually annoy the volunteers who work on CPython sufficiently that you may find it very hard to get any attention at all.

    Thank you.

    As for the pointing out: It worked for Cato, didn't it? He may not have lived to see it, but his perseverance in the face of rejection eventually brought about the years-long bloody war he had dreamed about.
