I downloaded ExcelWriter Plug-In and placed it in place as directed.

Pentaho 4.1.0

Whenever I drag Excel Writer from the output in design view I get:

Error creating step

I was unable to create new step

Class not found
org.typeexit.plugin.ExcelWriterStepMeta

When I click the details I get:

org.pentaho.di.core.exception.KettlePluginException:
