    Windows 11 and VB6 program problem

    Has anyone experienced a problem where a VB6 program just suddenly stopped working on Windows 11?

    I have two users that experienced this now and both have been using the program for a while without a problem. All of a sudden the program won't open. Clicking the icon just doesn't do anything. The program doesn't even show up in Task Manager. No messages or anything.

    The first user (South Africa) eventually reinstalled Windows 10 as well as the program and now it's working again.

    The second user's (China) experience started recently.

    I'm at a loss. Don't know where to start looking. Could Windows 11 somehow block the program?

    Any help appreciated.

    The application worked at first and then in a later session starting the application doesn't do anything.
    Have asked the user to check the properties of the application file?
    Check the file size, date/time modified, the version information.
    Maybe the file has been wiped by a virusscanner or MS Defender.

    I have seen this but not just with Win11. Something else is blocking the program from executing - 99.9% of the time it's internet security/anti-virus software.

    Yeah, I'm running VB6 compiled programs on several Win11 boxes, and I'm not seeing this problem.

    I have a few that's running on Win11. They've been running for a while and no problems found except for this two. And they have been running for a while already. The one in China since November 2023. The other one longer. And now this problem. I'm stumped. Just feels like a windows update that broke something.

    On the first one that gave the problem I checked and the exe is there and hasn't changed. Checked the quarantine of the antivirus and nothing there either. We even tried recompiling and reinstalling the program but still nothing. Tried reverting back to Win10 but that didn't work either. Then they formatted the harddrive and re-installed Win10 and the program and now it's working again.

    Start from Windows Event Logs -- Application, System, etc.

    I know that this cause is very unlikely, but... Have you done an analysis of which applications were installed on these computers, after yours, and before the problem appeared?... In particular, can you determine which was the last one, prior to the collapse?... Could there be an application installed in common in both cases?... Nothing to do with this problem, but for example, I installed Office LTSC 2021, and it ruined the installation of VB6 IDE, and the Office 2003.

    Have asked the users if they made any changes or installed anything prior to the problem starting. Waiting for reply.
