Windows installation instructions for Maud 2.67 and higher

After downloading the archive, unzip the and put the content (directory Maud) where you want to install it.
The directory should have the following structure:

  • maud.bat (double click this to start Maud))
  • lib (directory with libraries)
  • licenses (directory with various licenses)
  • plugins (directory to extend Maud capabilities)
  • jre1.8.0_92 (the Java Virtual Machine needed by Maud)

Start Maud by double clicking the maud.bat.

On some Windows installation you may get an error message like:
WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0x80000002. Windows RegCreateKeyEx(...) returned error code 5.
The problem is due to the fact that java has no more the rights to create the Prefs key on the registry. But you can create it manually once and then there are no more problems.
Here are the steps:

  • Go into your Start Menu and type regedit into the search field. Start regedit.
  • Navigate to path HKEY_LOCAL_MACHINE\Software\JavaSoft
  • Right click on the JavaSoft folder and click on New -> Key
  • Name the new Key Prefs and everything should work.


  • Where is the structure.mdb database? In the new version all these accessory files are located in your Home directory under AppData/Local/maud and another copy is in the Maud examples folder, located at: Documents/maud/examples.

    There are no example files in the AppData/Local/maud, I followed the installation as instructed, added the key to JavaSoft, but no example files.

    • Matteo says:

      Examples actually end up in the main Documents folder of windows, not on App/Data.

      • admin says:

        Yes, thanks,
        this has been changed on the last version as there were problems for certain Windows installations to find the examples in App/Data.
        So now the examples are in Documents/maud, sorry for the trouble

  11. Vivek says:

    the javasoft folder is in HKEY_CURRENT_USER instead of HKEY_LOCAL_MACHINE. Do I need to move the registry key or edit some script in the software to look for the correct place in reg?
