I can't uninstall the current version, installer fails. How can I fix it?

  1. Remove the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\HHD Software\Elisabeth\Applications\HHD Software Device Monitoring Studio 5.0
  2. Launch the installation package to install the application (this time it will install correctly).
  3. Launch the installation package again to uninstall the software.
  4. Now you can launch the installation package once again to install a product and start using it.
