[Closed] Photoshop Dll missing for automation

Hi

I followed this link from LoneRobot
PhotoshopAutomation
Which is awesome and thanks by the way.
But
My harddrive failed and i now want to add the Photoshop Dll back to the project in Visual Studio, because the project does not know what Photoshop is now but unfortunately the Dll does not show in the COM list, any ideas why? Or is it located somewhere? I couldn’t find it with SearchEverything so im at a loss.

The only difference is that i am now on windows 10 and when it worked i was on Windows 7, would that make a difference?

Any help would be hugely appreciated
Thanks
Dave
