VMware vSphere API Requirement on the AdminStudio Machine
AdminStudio 2021 | 21.0 | Automated Application Converter
In order for Automated Application Converter to perform automated repackaging, it needs to communicate with the virtualization technology that you are using. If you are using VMware virtualization technology (VMware ESX or ESXi Server or a local VMware Workstation), the VMware vSphere API needs to be installed on the same machine as the Automated Application Converter. You can do this by either installing VMware Workstation on that machine or by downloading and installing the VMware vSphere API from the following location:

Note:When using VMware Workstation, it is recommended that you install VMware Workstation on the same machine as Automated Application Converter so that Automated Application Converter will use the version of the vSphere API that was designed for that specific version of VMware Workstation. Although it is likely that newer versions of the vSphere API will also work, it seems that the best approach is for Automated Application Converter to use the version of the vSphere API that was bundled with your version of VMware Workstation.
