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)
  • jre (the Java Virtual Machine needed by Maud)

Start Maud by double clicking the maud.bat.

First, if Maud does not start by double clicking maud.bat, most probably you don’t have a valid java version to run Maud. Please download Maud WITH java (the version “complete”). To check if you have the version with Java or without, check if in the directory Maud you have a folder named jre or starting with jre. If not present you downloaded the version without java.

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.

  9. Matteo says:

    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?

    I already finish following the instructions, but when i clik the maud.bat it still can’t running, only comand prompt appear. i’am not certain on the latest step because there was a folder named ‘PREFS’ so i can’t made a folder named ‘PREFS’ again. so i rename it with ‘NEW KEY PREFS’. what should i do next? thank you for your kindness help.

      Be sure you downloaded the Windows version “complete”, not the one without java.
      If double clicking maud.bat nothing happen, you probably took the version without java, but you don’t have a Java desktop version installed. The Java inside the your web browser IS NOT a valid java desktop version for Maud.
      Please download the version with Java, in the table column “Downloads (complete)”.
