    Hello Greg,

    Could you please share with us the link for offline installer as well?

    Hello Gevorg,

    Here is the offline installer

    We still do recommend anyone to use the C1ControlPanel, because it has access to more samples and products, and the offline installer may not work once the control panel has installed any of the same products.

    the background for my question is, I am building a .NET Core 3.1 windows forms application, and using ComponentOne latest edition for winforms.

    There are few windows forms controls become obsolete with .NET Core 3.1. Please find below link, for more information.

    For example ‘ContextMenu’ control is obsolete in .NET Core 3.1 and the better version is ContextMenuStrip, so I have replaced the occurrences of ContextMenu in my application with ContextMenuStrip control, and its working fine.

    But, Looks like even in the latest component one winforms edition, the control C1.Win.C1Command.C1ContextMenu which is still using the obsolete ContextMenu system.windows.forms control, and because of this I am getting below error message, at run-time. 'could not load type system.windows.Forms.ContextMenu.
