Hello @Vipin Madathum Padikkal
These are the only requirements I'm aware of for using gRPC per the Blue Prism documentation:"This is the default callback channel and requires HTTP/2. The application server and all interactive clients that connect to it must be running Windows 11, Windows 10, or Windows Server 2016 or later."
You can find this in the ACR Configuration Guide
As for OLEDB and the Access runtime, there is no requirement for the Access runtime unless you intend to connect to an Access data source using the OLEDB VBO.
