The error "The specified account already exists" is encountered when you are trying to install the same version of HEIMDAL™ Agent that you already have on your machine.
Unable to install because a newer version of this product is already installed
When the message "Unable to install because a newer version of this product is already installed" is displayed means that you try to install an older release of Thor but a more recent version is still running on the computer.
If you want to use a different license key, whether you upgraded from HEIMDAL™ Free or you have purchased a new subscription, there is no need to reinstall the application. You can simply open the HEIMDAL™ Agent then go to Settings -> General Settings tab and insert the activation code.
In case there are problems with HEIMDAL™ Agent and reinstallation is required, please go to Control Panel -> Programs and Features and from the list of programs select HEIMDAL™ Agent and uninstall it. Then continue normally with the installation process.
