    After removing a previous C1 installation, i'm trying to install C1 studios WPF edition from the C1 control panel. The packages are downloaded, but during unpacking i get the following error:

    <Installation Edition="WPF Edition" Version="20193.1.685" StartTime="8. 03. 2020 10:57:07" TotalFilesToDownload="31" Success="false" ReasonForFailure="UnZipError">

    </Installation>

    When trying to clean my PC with the ComponentOneCleaner utility, i get this error:

    An item with the same key has already been added.

    What can I do to resolve this?

    Best regards,

    Hello,

    Please again uninstall the ComponentOne using the latest CompoentOneControlPanel utility and install the latest version which is valid with your license using the same utility.
    You can download the utility from the given link:

    Hello Prabhat,

    I tried installing / uninstalling as per the C1 documentation available online. Since no C1 product is currently installed, the uninstall from ControlPanel obviously isn't available. I already posted about the error I get from the C1CleanerUtility. Both applications (C1 ControlPanel and C1 CleanerUtility) are the latest versions downloaded from the C1 website.

    That is the reason I posted about this issue in the first place, because none of the solutions available online is working for me.

    Regards,
    Gregor

    Hello Prabhat,

    I'm still waiting for a possible solution for my problem. Right now I cannot continue working, since I can't install the necessary components.

    Hi Gregor,

    From the log, it seems that the file may have been corrupted during download.
    I am not sure why. Does it happen even when you retry?
    You may use the offline version of the installer from https://prod-cdn.grapecity.com/c1installer/Installers/2019v3/C1Studios_20193.1.3.exe
    to install the 2019v3 version of WPF on your machine.
