Description:
Looking at the http://dev.mysql.com/downloads/windows/installer/ site, the version of MySQL Installer (5.6.26.0) has not changed since I last downloaded and installed it.  Why then does the daily scheduled program taskeng.exe always report “There is a required upgrade available for MySQL Installer.  To receive product catalog updates you must apply this upgrade.” ??

I am running 64-bit Windows 7 Pro SP1 and I do have an embedded space within my %USERPROFILE% environment variable, which I understand from another bug (#77965) may be one reason why when selecting “Yes” at this prompt, MySQL Installer then fails to install that required upgrade:

    Your product catalog was last updated at 22/06/2015 09:44:35

    Connected to remote catalog host
    Catalog download completed successfully
    Manifest not applied. Requires upgrade available and we are not running in interactive mode.
    Update done

    Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object.
        at WexInstallerConsole.Actions.UpdateAction.DoAction()
        at WexInstallerConsole.Program.Main(String[] args)

The OS then reports that MySQLInstallerConsole has stopped working and in another window, with the title “Windows Installer”, I see an error message (akin to a short response from msiexec --help) that suggests some incorrect command line parameters/values were presented when attempting to launch msiexec.exe.

I wonder though if the root cause for the failure to install the update is also related to the taskeng.exe program falsely reporting that a required update is available when one is not.  If not, is this a new defect?

How to repeat:
Wait till midnight for the next scheduled execution of taskeng.exe

Hello David Kubel,

Thank you for the bug report.
This is most likely duplicate of Bug #78138, please see Bug #78138

Thanks,
Chiranjeevi.

Getting the same error. is there a fix released for this ?

In my personal opinion, it seems like you're encountering difficulties with the MySQL Installer on your 64-bit Windows 7 Pro SP1 machine. I genuinely sympathize with your situation.
From the details you provided, it appears that the version of MySQL Installer (5.6.26.0) has remained unchanged since your last download and installation. However, there's a daily scheduled program called taskeng.exe that consistently notifies you about a "required upgrade available for MySQL Installer" and prompts you to apply it. This recurring message can be quite frustrating.
It's possible that the issue lies with taskeng.exe falsely reporting the availability of an update when there isn't one. But it's hard to say for sure without more details. If you're still facing problems, another option you can try to check this source: https://andersenlab.de/blueprint/software-architecture-importance This measure aligns with the understanding that robust software architecture plays a critical role in ensuring seamless performance and efficient functioning of software tools.
