Why do I get 'Setup Has Ended Prematurely' when trying to install LogMeIn Hamachi?

« Go Back




You see the following error:
Setup Has Ended Prematurely


This can happen if you had a previous install of Hamachi on the system that was not uninstalled properly. 


Search Windows (including in Hidden and System files) for any folders called Hamachi or LogMeIn Hamachi.   Delete these folders and try reinstalling again. If the install still fails, there are probably some old registry settings preventing the install from completing.  You will need to edit the Windows Registry to resolve this.


Please use care when modifying the Registry.  If you are unfamiliar, please seek assistance or contact LogMeIn support.

  1. Press and hold the Windows key and press the R key.
    The Run box will appear.
  2. Type regedit and press Enter.
  3. Click the drop-down arrow next to HKEY_LOCAL_MACHINE.
  4. Click the drop-down arrow next to SOFTWARE.
  5. Look through the list for any entries named Hamachi or LogMeIn Hamachi and delete them.
    You may also want to look under Applied Networking (if it is there) for any Hamachi entries, and delete those as well.
