Hello,
I have been trying to update a classification scheme I've made and it keeps failing. I've saved the progress in the training sample but I can't select the tool anymore. I've tried restarting my computer and it won't help. I don't want to start a new project because there are so many layers I don't want to convert them all then upload to a new project.
Is the image selected in the table of contents?
There are two situations where it is disabled

The Classification Wizard is disabled if the active map is a 3D scene, or if the highlighted image is not a multiband image.
Of course, you could always skip the wizard and use the underlying tools, for example:
