PDF Split Error


I had developed the process on 2018.4.1 and then deployed it in a version of 2018.2.3 on the Client machine. I used PDF split activity for splitting the PDF. I included the package PDFSplitPackage on the client. When I run the process through studio, it works just fine. But when I run it through orchestrator, I see that it throws error in the log "system exception: cannot create a type of PDFsplit.
Please help with this issue. Looks like PDFsplit is compatible with 2018.2.3 as I am able to run it through studio but cannot through Orchestrator even after including dependent packages.
