To have security access to uninstall a module, you must login as the host manager account (default name is host), go to the host menu and select the Module Definitions.

Inside the Module Manager, edit the module by pointing the mouse to the edit image (pencil) next to module name. Towards the middle of the page, check the "Delete Files" checkbox if it's available and then click on Uninstall link.

Your module is now uninstalled.

Important Note: Many of Mandeeps.com modules depend on shared files that are used between modules. Prior to DotNetNuke 5.0, these files are deleted when you uninstall any module that is dependent; which results in other modules throwing an error looking for file. If you're running a version prior to DNN 5.0 then ensure all other mandeeps.com modules are working correctly after uninstalling this module. If any particular module is throwing an error then simply reinstall that module.
