CANNOT SOLVE MISSING COMMON.DLL - Anyone HELP!

[csat]

Visual Studio 2017

Loading older project file

All ok except the references say it cannot find NationalInstruments.Common.DLL version 8.6.35.131.

I have all the dll's from the older project and it loads all the rest fine

NationalInstruments.Common.DLL                 version  8.6.35.131  -   System cannot find....

NationalInstruments.UI.DLL                            version  8.6.35.189  -   OK

NationalInstruments.UI.Styles3D.DLL             version  8.6.35.189  -   OK

NationalInstruments.UI.WindowsForms.DLL   version  8.6.35.189  -   OK

How to get the  correct DLL !

This is holding the whole project up..

Cheers
