I just installed Eclipse 2020 0606 on an HP elite 8000 desktop system running Windows 10.

I can't edit some of my source files.
Particularly, these are files that I originally made using the Design View and associated tools.

When I click on a source file in the Project Explorer that was not created using the design view, all seems normal; however,

when I click on one of these files, instead of showing the source file, the box in which the source normally appears has the message "No editor descriptor for id org.eclipse.wb.core.guiEditor"

I will be the first to admit that I do not understand the internal tables that Eclipse uses. This should not be an uncommon phenomenon, as I haven't ever been able to find any documentation on these and must assume that others have encountered similar difficulties.

How do I get Eclipse to properly edit this old source code?

I was able to resolve the issue by reinstalling the plugin.

I was reticent to do this because I was having trouble installing it on another computer in my residence.

But I didn't get everything back.

The code that I had previously edited using the WindowBuilder Plugin no longer had a "Design" tab.

Is there some way to force Eclipse to use the WindowBuilder? Could someone please direct me to documentation on the WindowBuilder plugin?

You can generally use Open With -> from the context menu to choose which editor opens the resource.
