SAMI can't find SA directory

[burnm3w1thf1r3]

I am having trouble using San Andreas Mod Installer (SAMI). I bought the RockStar game pack through steam (GTA 1,2,3,4 VC,SA) I had no issues modding GTAVC or GTA3 however when I go to use SAMI with GTASA upon starting SAMI I get an error reading:

"The installation directory for San Andreas could not be detected because it doesn't exist in the registry. Please use the "browse" button to specify the correct directory."

So I click 'ok' and SAMI starts. I choose 'Install Mod" and where the San Andreas Directory path is, it defaults to:

"C:\Program Files\Rockstar Games\GTA San Andreas\"

I choose browse and navigate the path to:

"C:\Program Files\Steam\steamapps\common\grand theft auto san andreas" where my gta-sa.exe is.

And upon clicking detect I get this error message:

"The installation directory for San Andreas could not be detected because it doesn't exist in the registry. Please use the "browse" button to specify the correct directory."

I have tried uninstalling and reinstalling GTASA and the error persists. Please help!!!!
