Lao Script for Windows Version 6 and Windows Vista

Lao Script for Windows Version 6 was developed several years before the release of Microsoft® Windows Vista, and although it can be installed, does not work correctly. Unfortunately, when Version 6 is uninstalled from Windows Vista, it can sometimes leave behind some components which prevent Lao Script for Windows Version 7 from installing or working normally. The following instructions advise how to remove those residual components.

The following instructions require making changes to the Windows Registry. If you are unsure how to use the Windows Registry, we recommend that you get help from a local IT consultant.

Manual Removal of Residual Components

• First, follow the standard uninstallation procedure using Control Panel - Programs and Applications.
• Open Start – Run, or open a Command Prompt window, and type regedit.exe to start the Registry Editor.
• Delete the registry value LSWin LaoKey from the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run.
• It is best to also delete the entire registry keys HKEY_LOCAL_MACHINE\SOFTWARE\LSWin and HKEY_CURRENT_USER\Software\LSWin if either has not been removed during uninstallation, but they will not normally cause difficulty if left undeleted.
• Restart the computer. This is essential to release locked files - do not simply exit from Windows then re-open it.
• Delete the Lao Script for Windows application folders [Program Files]\LSWin
  and Users\[user]\AppData\Local\VirtualStore\Program Files\LSWin if either still exist, where [user] is your logon name.

If these instructions are followed, you should then be able to install and use Lao Script for Windows Version 7 normally.
