How do I pin a different version of Eclipse to the window taskbar?

I have to use a different version of Eclipse instead of the previous version. I was writing with the old version pinned to the taskbar, but I tried to remove it and fix the new version to the taskbar, but the version that I fixed earlier is being pinned to the taskbar.

When you run Eclipse in all three of the above methods, from the step of selecting a workspace, the existing Eclipse icon appears in the taskbar instead of the new version of Eclipse, and the Eclipse that you run through this icon is also the old version, not the new version.

Is there any other way to fix the new version of Eclipse to the taskbar instead of the previously used Eclipse?
