Hi Jeet,
sorry to hear you're facing problems.
This is the main web page for MIR Pro: -> https://www.vsl.co.at/en/Vienna_Software_Package/Vienna_MIR_PRO
These are the RoomPacks you need to run MIR Pro (... think of it as "the samples" and "the sample player engine"): -> https://www.vsl.co.at/en/Vienna_Software_Package/Vienna_MIR_RoomPack_Bundle
... and this is MIRx, a software add-on that can be used exclusively by Vienna Instruments: -> https://www.vsl.co.at/en/MIRx/MIRx_Bundle
I don't know _what_ you bought, I was just referring to the screen-shots you supplied. They clearly reference to a MIRx product. MIRx is not compatible with MIR Pro, as pointed out above.
If you think that you have bought licenses for the wrong product, please get in contact with sales@vsl.co.at . I'm sure VSL's sales team will sort out the issue for you swiftly.
Kind regards,
