Answer

Symptom

When trying to install LogMeIn, you receive an Error 1920 message.

Cause

A 1920 error is caused by a third party software or windows blocking LogMeIn from accessing any of the default install ports used during installation.

Resolution

You must manually install the LogMeIn Software

Task One: Download the software

  1. Download the installer: https://secure.logmein.com/logmein.zip.
  2. Save the zip file to your desktop or any other preferred location.
  3. Extract the files to C:\LMI (you may need to create this folder on your C: drive).

Task Two: Remove all elements of the LogMeIn software

Important: Be careful when editing your computer's registry! Feel free to contact LogMeIn for assistance. 

Tip: If you receive an Access Denied error at any step during this process, restart the computer and continue the process.
  1. Terminate LogMeIn services running on your computer. To do this, open the Task Manager and terminate all instances of the following:
    • LMIGuardian.exe
    • LogMeIn.exe
    • LogMeInSystray.exe
    • ramaint.exe
  2. Navigate to your Program Files folder and delete the LogMeIn Folder (usually under C:\Program Files).
  3. Open the Registry Editor by pressing Windows+R and typing regedit in the Open box.
  4. Navigate to HKEY_CURRENT_USER\Software and delete the LogMeIn folder.
  5. Navigate to HKEY_LOCAL_MACHINE\Software and delete the LogMeIn folder.
  6. Navigate to HKEY_LOCAL_MACHINE\System\Current Control Set\Services and delete the following:
    • LMIInfo
    • LMImaint
    • LMImirr
    • LMIfsClinetNP
    • LMIRfsDriver
    • LogMeIn
  7. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run and delete the LogMeIn GUI string value.
  8. Restart the computer.

After restarting the computer, LogMeIn should be uninstalled.
