Cannot edit .MTA, Menta is in 'Stand Alone' mode


Getting error message in Vista that Menta is in 'stand alone' mode and cannot edit the .MTA


  • Vista
  • Menta


This happens usually when Menta has previously been installed on the system in a "stand alone" fashion and then Vista was installed at a later time.


  1. Go to Start > Run and type "regedit" to open the Registry Editor
  2. Navigate to HKEY_LOCAL_MACHINE > SOFTWARE > TAC > TAC Menta
  3. Double click the key named StandAlone.
  4. Change the value data to "No"

For a 64 bit OS, the path in the Registry Editor is HKEY_LOCAL_MACHINE>SOFTWARE>Wow6432Node>TAC Menta
