Ever install a DNN module and then your whole site goes down? If after you install a DNN module and then get a .NET error like “Required permissions cannot be acquired” (turn “Off” customErrors in your web.config file to see full error), then you can manually delete the module files you uploaded (in the “DesktopModule” and “Bin” folders) to get your DNN site back up. Once your site is working again, login and uninstall the module in the “Host / Module Definitions” interface.
