I know this may be a long shot but this is what is happening and if anyone can please help it would be greatly appreciated.

I installed Porting Kit and GOG Galaxy. I bought the game from GOG.com. Followed the instructions from Paulthetall. I had to create a new port for the game. Set up Pharaoh through the wrapper and it plays. Played it all yesterday and now when I go back to it, it says it is missing components from GOG Galaxy and to please reinstall the application. So I did....same thing keeps happening.

I open GOG Galaxy and find my game in the library but even there I cannot install the game as it comes up on the tile 'not compatible' in red on the bottom right hand corner. Click the drop down menu and click on install and it just sits there loading. Can someone please help me and tell me I am missing something stupidly small here?? :'(

Simplify your life and use the Classic Installers, sans Galaxy, under More. New prefix/bottle and reinstall the game. You may be able to beat Galaxy into shape, but easier to just skip it entirely.
