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

Start Maud by double clicking the maud.bat.

The following problems should not be present from version 2.84 or higher using the new Java 11. In case you find some, please check the notes below and post a comment.

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.

  1. 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.

      • 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

  2. 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?

  3. Hi I am using Windows 10. I am not able to get JAVA soft location under path HKEY_LOCAL_MACHINE\Software
    What to do, kindly suggest.

  4. 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)”.

  5. Hello. I installed the software in my laptop that has windows 10. I create the path into the machine/software and it opened without showing that error code.

    But when I loaded the file, there is a error that says “spectrum not loaded”. I did this with one of my files and one of the files in the example folder.

    Do you know what the problem is?

    Thanks in advance.

  6. Hello:

    I installed the software in windows 10. There is an issue with the font and size of the icons used by the sotware, they are tiny. Do you know how to fix the problem?

    Thanks in advance

  7. I encounter the same problem. I think it is due to the change in the structure of the regedit in Windows 10, Java Soft is now at –> HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\JavaSoft\
    and the maud file is searching for the prefs folder at HKEY_LOCAL_MACHINE\Software\JavaSoft. So after adding the prefs folder and downloading the right file, how do I solve this problem?

  8. Hello. I finished downloading Maud, but I’m running into problems when I try to run the HIPPO Wizard. Once all the data sets are loaded, no plots are displayed, and when I click on an individual data set it directs me to change its name. I also get this error “Spectrum not loaded. check the datafiles”, but I’m not sure what other data files to load after the calibration file and the example data files.

  9. I am facing in opening maud.bat file.
    I download both complete maud file and without java, bu maud.bat file cannot run

    • Difficult to say without more info on what you are trying to do and the cif files you have. Have you tried to post the problem in the Maud Forum (see link page).

  10. Hi Luca, I used to have MAUD configured to go straight to the proper folder or file. i.e. when I started MAUD it went to the last .par file I was using. Or, when I tried to load an *.cif file it went straight to the folder I was already working in. How do I fix that?

    • Hi Raul,
      it was disabled in one of the versions, but now is back in one of the last versions.
      Check in the Maud Preferences that “analysis.loadLastAnalysisAtStart” is set to “true”.

      ciao Luca

  11. Dear i had downloaded moud complete softwear but still it is not instaled. i had not find Maud.bat button.
    My mindows is 10
    Please help me
    I need maud

    • There is no installation, after you unzip your, you have a Maud directory, inside there there is a Maud.bat file, is not a button. Double click that file to start Maud.

  12. I’m having the same problem with .par files as Martin above (I’m also running Windows). Additionally, when I change the path to my database folder in the Preferences section, it has no effect (although the new path is stored). I am using the following format: ‘C:/Users/me/work/rietveld/’, and I’ve also tried using ‘//’ at the start of this, but with no luck.

  13. I started to use Maud in order to refine some Synchrotron data. I could use it very well first week, but then something unexpected happened when opening Maud. The first view when opening the program has not the default dataset “DataFileSet_X” available to edit and I could not generate a new file. When I select “File—>New—>General Analysis”, nothing shows up in the left box of the view. I tried several times but, there is not Dataset file in the screen to edit.

    I would appreciate if you could give me some tips to solve this problem, since I did not find any helpful tutorial related with this situation.

    Thank you in advance.

  14. There is no ‘structure.mdb database’ at AppData\Local\maud\doc, and also no ‘Documents/maud/examples’. Could you help solve this problem, thanks.

  15. Hi! I just downloaded version 2.94. I could not find “structure.mdb” at AppData\Local\maud\doc, nor the folder ‘Documents/maud/examples’. I did not have the “Structure.mdb” file anywhere in version 2.93 either, although I did have the “Examples” folder… Thank you!

  16. I don’t see MAUD.bat file after unzip the downloaded zip file. I have downloaded “Downloads(Complete) ” file.
    Please advise me what I was wrong in downloading. The OS of my laptop is Window 10.

  17. Hi, I have recently installed Maud. When I open the maud.bat file I get the following error.
    Warning: No leading – on line 1 of Maud\jdk\lib\jvm.cfg.
    What does this mean?

  18. Hi. I download the complete version of 2.94, Maud does not start by double clicking maud.bat, and I can’t find any folder named jre or starting with jre in the directory Maud.

  19. Hi, I download the complete version of Maud 2.94, but Maud does not start by double clicking maud.bat. I can’t find any folder named jre or starting with jre. WHY?

  20. I get an error message
    “Start rita/rista function computation
    Computing spectra for sample: Sample_x
    Error in the computation, check the java console window for more details
    Have a nice day (if you get it working)!
    My input files work on other computers with similar Win 10 Pro, also MAUD 2.94 (re-installed today)
    There is no message in my “java console window” (the DOS box that appears when I first start MAUD)
    Tried modifying the registry in WOW6432Node by adding “Prefs” folder under JavaSoft, no help
