There are several methods/options to uninstall LiteSpeed.
To uninstall LiteSpeed (Versions 4.x):
If the LiteSpeed2005.msi installer is available and was used to install the LiteSpeed application, run it again. If the same version is installed, the application will prompt the user to uninstall the application.
Use the 'Add and Remove Programs' windows utility under Control Panel to uninstall the application.
Use uninstall string from the following path in regedit:
Find LiteSpeed from the list of GUIDs and double-click on the 'UninstallString', The 'Edit String' window will appear. Copy the 'Value data' into a command prompt. This will start the uninstall process. This is the same process that is run during Add/Remove programs from Control Panel.
Perform a manual uninstall of extended stored procedures, .dll files, .exe files, databases, folders and registry keys.
Note: Before un installing LiteSpeed, unlink the LiteSpeed Repository databases if you have LiteSpeed Activity logging enabled. Using the 'Instance Configuration' tool, under the Activity Logging screen, select 'Do not setup Activity Logging at this time'. Go through the remaining steps to complete the process.
