Solidworks Explorer not in Windows Explorer

I recently updated to SW 19 package including SW19 Explorer. however I seem to have lost settings. now when i use my windows explorer, I cannot access SW Explorer from the drop down options. 

Does anyone know how to add SW Explorer back into my Windows Explorer ?

I use Explorer Daily and despise the aspect of having to run both explorers all day long. 

Can someone please help!

Thank you,
