KeyShot installers allow you to migrate previous version resources to the new version if you have already done that you should be able to see RenderShot Submitter script in your new KeyShot scripting console and so you do not need to redo these steps, please use the migrated version and it should work as expected!
Open KeyShot scripting console.
Import a new script file
Select the script download from RednerShot and ensure its the correct migration version.
