Unable to install or uninstall Dameware MRC

Been trying to install DW MRC v12.0.2.3 on a number of machines which initially install fine... however when uninstalling, and removing any traces of the files on the system result in unabling to re-install the software.

Upon reinstalling, or even installing on new machines, i get the same 'There is a problem with this Windows Installer Package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor. Action APPDIR, location: C:\Program Files\SolarWinds\DameWare Mini Remote Control x64\, command: "C:\Program Files\SolarWinds\DameWare Mini Remote Control x64\SolarWinds.MRC.Licensor.exe" 

I tried downloading different releases of MRC to no avail.

Looking on logs and event viewer suggest errors relating to the  licensor.exe file. I can see a number of people on the forum and Google have had this issue but no resolution/replies.

Any advice appreciated
