This question already has an answer here:
I've made a Visual Web Part in Visual Studio (non-sandboxed) that I could easily deploy & "debug" on my local SharePoint installation.
I want to copy this web part to another SharePoint installation, so I went ahead and right-clicked the project in Visual Studio, clicked on the Publish, and saved it to the drive. I got a .wsp file.
I've taken this .wsp file and copied to the other server, installed with Add-SPSolution & Install-SPSolution
I don't see the web part in the Web Part gallery.
How can I get it there? What steps am I missing?
