Datasmith can't find my SketchUp on install

I have 2 PC’s (windows 10 64bit) I have SketchUp Pro installed on both and SketchUp in installed in the same place.
C:\Program Files (x86)\Trimble. Inc\SketchUp Pro 2018\Sketchup Pro 2018
I try to install and I get “No supported version of SketchUp Pro has been found” on both computers.
Help, please.

Hello.

Please contact our Unreal Studio support at the link - https://unrealstudiohelp.epicgames.com/s/case-community-page

Thank you

When I try to install the Datasmith exporter for SketchUp a popup window says “no supported version of SketchUp pro has been found”. I haven’t finished downloading UE 4.26.2 yet. Is that the reason I,m seeing this message?
