Occasionally, the Lao fonts do not seem to display correctly after Lao Script for Windows has been installed. If you are having difficulties, first of all open the Windows – Fonts folder (from Control Panel) and refresh the window (press F5).  Usually this is all that is needed to make the fonts display correctly.

In very old versions of Lao Script for Windows (before Version 4), the Lao fonts were installed in a separate directory, and only linked to the Fonts folder.  If you have upgraded from such an old version and the font links still exist, they may prevent the newer fonts from displaying correctly. In that case, you should identify the old fonts by their names and the shortcut mark in the corner of the icon in the Fonts folder, and delete the shortcuts to those fonts, which should correct the problem.

If fonts still fail to install correctly, manually remove all old versions of the fonts being installed, then re-install Lao Script for Windows.

A separate but related issue is if the fonts appear garbled. If that happens, in most cases it is because the wrong input encoding has bee selected for the font in use when entering Lao text. Please see the discussion of Lao font convenions and input encoding in the Lao Help Menu for further information.
