Okay, so none of the installer fixes would work for me.. not deleting the files using SSH or anything. Now you're wondering why I wrote SKYLER READ on the top. Let's put 2 and 2 together. SwapFonts.app. I changed the system font using it. Installer wouldn't open. I set it back to default, and now installer opens. So skyler if you could make a fix for this, and for those of you having troubles I hope this helps.!
