LiteSpeed installs a number of Stored procedures into the Master database for it to function correctly. Performing an Uninstall using the Control Panel does not uninstall the Stored procedures.
Carry out the procedure below first before un installing the product through Control Panel.
The LiteSpeed objects can be un installed using the Instance Configuration. Open the Instance Configuration Wizard and on the second screen SQL Instances you will see a list of instances that has been detected. Under the column install actions choose the option to Uninstall. This will uninstall the objects from the SQL Server Instance.
Please note that this will not remove any LiteSpeed repositories that you have. If you need to remove these you will have to do this manually.
You can then uninstall the product by choosing to do an uninstall through Control Panel.
