I d/loaded Baldurs Gate Enhanced and cant find it to install it. This is my first GOG d/load and im a bit lost. Not PC literate at all just an old guy that likes to play game. Any help will be appreciated.

Do you have a "Downloads" icon\menu in your browser?
You should check that, first of all.

Did you download via browser? If so then you will have each of the files (it may one just one part or several parts) will likely have been saved into your Download folder (open Windows Explorer and on the left you will see Documents and Downloads amongst others). Open downloads folder and double click on the Exe - this is the first part and is there to unpack itself and all the other parts. You will need to provide a location to install and then let the installer do its work. A shortcut will appear on the desktop. Keep the downloaded files, you can keep them on an external hard drive or usb or something like that - this is the big benefit of DRM free as these files are now yours, you can install when you like, without any other hoops to jump through or internet connection.

Note if you get a warning saying xyz is missing, make sure you downloaded all the parts of the game from your Account.
