    Designer fails to load when a new FpSpread is created on a form with:

    Microsoft Visual Studio
    Failed to create component 'FpSpread'. The error message follows:

    Can you try to re-install Spread and then try? Re-installation might resolve the exception.
    If the issue persists, please share the Spread version you are using along with OS version.

    Finally I found the problem.

    I was trying to add a FpSpread in a x64 project, what seems not being currently supported.

    In a x86 project there is no problem.

    Just a comment to say that maybe you can try to create a version that will support both, x64 and x86 projects. If I am right, most current machines are x64 architecture.

    Hi Juan,

    FpSpread does support x64 architecture. I verified this at my end using VS19 and dropping the control onto a form of a Windows Forms project targeted for x64 solution platform and it works properly.

    I installed visual studio 2022 x64. I am creating a win form .NET framework project. I get the same error and adding the spread to a form. Does this mean that I need to use the x32 version of visual studio 2022?

    Hi Peter,

    Could you please let us know what version of Spread you are using and what version of .NET Framework you are targeting?

  • Replied 28 April 2022, 10:27 pm EST

    I am using Spread version 15.1.20221 targeting a WinForms .NET Framework 4.8 App.

    I just created a brand new forms project using the start screen and tried adding the control as the very first action.

    OK, I have more information for you. If I launch the spread designer on its own. I can turn off auto launch spread designer on new instance of spread. If I do that I can put the spread on the winform in VS2022. However launching the designer from within visual studio results in this

    First, please uninstall the older version of Spread 15, if you have it already installed. Then make sure you follow the steps given in the readme file.
    You need to copy the files to C:\Users\[username]\AppData\Local\GcInstaller\Offline. Then when you run the Installer you need to change the mode to offline, the installer will show version 15.1.20221.1 as shown in the screenshot attached.
    We followed the process at our end and the spread worked fine with its designer.

    It's working, must be uninstalled the old version first.
