I can’t find a create new project anywhere. help me
Katalon Studio went in a direction that they wanted everyone to use another of their products, Katalon TestOps, from which you would create a project and then work on the project with KS. Since then, they have released another version of KS that is a stand-alone, which I believe is called Katalon Studio, Stand Alone Edition (or Personal Edition). I think that is the version that you need to down-load to be able to create projects.
