EEDK uninstall task doesn't work

[NqkoiNqkoga]

Hello guys,

using EEDK I have created a deployment package for a software that we use in our environment. It is just an executable and I had no issues to create the package, check it in EPO Master Repo and deploy it  with a client task. However when I try to run an uninstall task from EPO on the local MA Status Monitor it gives me an error that it dosn't find a plug in key; Does anyone know how to workaround this? Is it mandatory to use batch files?

the EEDK version is 9.6.1 Enterprise;
