How to Install Khmer Unicode on your Windows XP Computer

This tutorial will walk you through the process of enabling Khmer Unicode on your Windows XP computer (if you need help installing Khmer Unicode on Windows 7 click here).

First download this file and then run the file – when you do you should see something like the following:

Now click the “Next >” button as shown in the picture.

Click the “Next >” again (if a box telling you that the directory does not exist pops up, just tell it to create the directory).

Now click “Exit” (it is possible the “Windows File Protection” box might pop-up before you can click “Exit”, if this occurs, go to the next step to deal with the “Windows Protection” box and then once you are done, click the “Exit” button on the Installer window.

When this box pops-up click “Cancel”

When this box pops-up click “Yes”

Now go here and download the latest Khmer Unicode Install Program (currently it is version 1.2.5) and once it is finished downloading, run the program. When you run it you should see something like the following:

Click “Next”

When this box pops-up click the “Complex & kbd” button (this can take a few moments to install, so please be patient). It is possible that you will need your Windows XP cd at this time – so if you are asked for it, please insert it into your cd-rom.

When the text “Complex script enabled/Keyboard layout added.” appears click the “Close” button.

To finish off the installation, click the “Exit” button.

Now you should see a new button in the lower right corner of your screen saying either, “EN” or “CA”. When you want to type in English, make sure “EN” is showing, and when you want to type in Khmer Unicode, make sure the “CA” is showing. To switch between the two languages, you can click on the button and select (like the picture above shows), or you can press the “Alt” key and the “shift” key which is on the right hand side of your keyboard (if you press the “shift” key that is on the left hand side of your keyboard it will not switch).

    how can it be solved?

    some one says that mule-ucs will handle this problem. but how to find Khmer mule-ucs?

    • admin

      Hello Hyp.M,
      I have heard some people have had success using Khmer Unicode with Quark XPress 8, but I don’t believe it works with either version 5 or 6.

    Dear Khmer Unicode Creator!

    I have a lot of problem with Khmer Unicode. How to type Khmer Unicode in all program? Is there any Solution? Please Show how! Thank In Advance!

    • admin

      Hello Seng,
      Many programs do not yet support Khmer Unicode – we will just have to wait until more support it. If you use the latest software (windows 7, office 2010 etc.) you will have a better chance of unicode working in the programs.

  • khidhir

    Hi, does khmer unicode support office 2007?

    • admin

      Yes it does – quite well. But it doesn’t include a Khmer spelling checker.

  • Rith
    • admin

      Are you using Windows 7 or Windows XP?

      From my understanding and experience, using justified never works out all that well with any Khmer font – but if you send me a file and a screen shot of what you see, I can take a look – sunkhum at gmail

  • PJ

    Hi ! I installed khmer unicode successfully. And when I opened khmer unicode watcher, I saw all checks. But I can’t read the file with khmer fonts. I saw a sign like this [][][][][][][][][][][][][][][]. How to solve this problems ? Thank you !

    • admin

      Those symbols normally mean a non-Khmer Unicode font is being used. Can you change the font in the document to Khmer OS or another Khmer Unicode font and see if that helps?
      Let me know if that works,

  • sarith

    i already completed the installing but i write khmer unicode in Microsoft
    Power point letter is separated long distance. So please you guide me too,
    thank and best regard

    • admin

      Hello Sarith,
      What version of Power Point do you have? If you have 2007 or 2010 things should work fine. Also try using different fonts and see if that helps.
      Let me know if you still have trouble,

  • Chan Thol

    Somebody can help me?
    i install khmer unicode on windows xp and office 2007. When i try to switch
    keyboard to khmer unicode the microsoft office word is stuck.

    please help to advice.

    • admin

      I’ve never used Windows XP and Office 2007 – it actually shouldn’t have issues as Office 2007 is fully compatible with Khmer Unicode…what version is your usp10.dll (search for it in Program Files, and make sure you are searching hidden files just in case)? It should be at least version 1.624. Back up your usp10.dll and then use the one in this extractable file from Microsoft and see if you have any more luck.

  • narong

    who can help me about “version usp10.dll”?

  • Pagna

    Hi there;
    I installed Khmer Unicode 2.0.1version. But when I typed it’s still in English and I couldn’t find the ” EN” or ” CA” on my task bar to switch. Can anyone tell me how to solve this? Thanks!

    • admin

      Hi Pagna, if you are on Windows XP (I am on Windows 7, so I can’t give exact directions) Click Start, type intl.cpl in the Run box, and then press ENTER.
      # On the Languages tab, click Details.
      # Under Installed services, click Add.
      # In the Input language list, click Catalan
      # In the Keyboard layout/IME list, you should see the option for a NiDA keyboard, choose that one.
      and then click OK.
      See if that helps.

  • Pagna

    Hi Nathan;
    Yes, I’m using Windows XP. I followed your instruction, but when I was on the ( # in the Keyboard layout/IME list,…..) I couldn’t find the option for a NiDA keyboard. What can I do next?

  • Pagna

    Hi Nathan;
    I just found it ” Khmer Unicode Keyboard (NIDA1.0).


  • Pagna

    It works ! I can now type the Khmer Unicode.
    Thanks again Nathan!

    • admin

      Hello, you can try downloading a newer print driver for your printer. Also you can try to type in notepad and print to see if the same problem occurs. Also try using different fonts to see if that fixes the problem. Let me know if that works.

  • Mengthoin

    In notepad also can’t c it ( still lost legs).
    Its done by changing another printer (HP laser jet 1020), if m still
    using (HP Laste Jet 1005) it won’t work.
    Now m finding out other software to upgrade HP 1005 !
    also m trying connecting HP 1005 to another PC or Laptop that have font
    Unicode for trying printing its again.
    If it won’t work maybe HP Laser 1005 againts with Unicode.

    Click Retry to try again, Ignore to skip this file (not recommended), or Abort to cancel installation.

    do u have any new version khmer unicode for Ubuntu?
    I can’t use khmer unicode in Microsoft word program on Ubuntu system. Can u deal this problem for me?

    • admin

      There are no new versions of Khmer Unicode because it already is working. Microsoft Office Word does not work on Ubuntu – unless you use something like WINE:

      But I am still not sure if there would be full compatibility.

      If you want to use Microsoft Office, it would be better to use Windows 7. And if you want to use the spelling checker and grammar checker for Khmer, use OpenOffice or LibreOffice (both of which work in Ubuntu and Windows).

      Were you installing or uninstalling? I would recommend Windows 7 (or very soon Windows 8 – as that will only be a $40 upgrade from Windows XP).
