Why?: Because by default, macros are saved to the same directory MacroGamer is installed, "/Program FIles (x86)/MacroGamer". The Windows account you are using must have Write permissions to that folder. Non-admin Windows accounts do not have Write permissions in most scenarios. Try one of the solutions below.

• Solution 1
• Download and install the latest version.
• Solution 2
• Reinstall MacroGamer in a different location instead of the default, "/Program FIles (x86)/MacroGamer". Try installing it under My Documents, C:\Users\<your windows account>\Documents.
• Solution 3
• Run MacroGamer as Administrator by right clicking on the shortcut and selecting Run as administrator. Note: This should be a last resort.
