Repairing a GSX Gizmo Installation

We observe installation error messages when upgrading or reinstalling GSX Gizmo with a user account that is different from the user account of the initial install. When this occurs, the easiest way to resolve the issue is to follow a manual procedure to restore the Operating System (OS) to a state that will be able to accept the GSX Gizmo installation or upgrade again.

GSX Gizmo 1.0.x


  • OS and installation Logs contain error: Product: Gizmo -- Error 1722
  • 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. 

How to Solve the Issue 

Restoring the OS to a state that will accept the GSX Gizmo installation includes removing GSX Gizmo installed programs, cleaning temporary and program folders that contain traces of the GSX Gizmo programs, possibly removing associated Windows services manually, and lastly rebooting the GSX Gizmo station at the OS level.

Prior to starting the procedure below, ensure first that Node.js is no longer running on the GSX Gizmo host machine. Using the Windows task manager, check that:

  • no "node.exe" process is running nodejs.png
  • no "nssm.exe" process is running

Uninstall software installed by GSX Gizmo:

  1. Open the Windows Control Panel.
  2. Find Program and Features.
  3. Uninstall the following:
    • GSX Gizmo
    • Apache CouchDB
    • RabbitMQ
    • Erlang
    • Node.js

Cleaning temporary folders that contain GSX Gizmo related programs:

You may experience issues deleting files created by Gizmo as they are stored deep down in the OS folder hierarchy and reaching a known Windows limitation. If that is the case you will need to use Robocopy to delete files the OS cannot delete on its own without assistance. Check "How to Clean Folder Contents when a Filename or File Path is to long" for detailed information.

  1. Open the Windows File Explorer
  2. Navigate to the \Users\<username>\AppData directory.
  3. Remove files located in the following sub-directories:
    • \Users\<username>\AppData\Local\Temp
    • \Users\<username>\AppData\LocalLow\Temp
  4. Navigate to the \Users\<username>\AppData\Roaming directory.
  5. Locate and clean any of the following folders found in the \AppData\Roaming directory GSX_Gizmo_data_in_Roaming_profile_1_002.png:
    • Apache CouchDB
    • Erlang
    • Node.js
    • RabbitMQ
    • Gizmo
    • GSX Solutions
    • NPM*

Checking for GSX Gizmo related Windows Services still present:

  1. Run Services.msc to open the Windows Services manager.
  2. Notate if any of the following GSX Gizmo related Windows Services are present:
    • Apache CouchDB
    • Erlang
    • Node.js
    • RabbitMQ
    • Gizmo

Stop and uninstall notated GSX Gizmo related Windows Services from an elevated Command Prompt:

  1. Click the Windows Start Menu and type cmd.exe.
  2. Right click on the Windows Command Prompt and select "Run as administrator".
  3. Run the following command adding the notated GSX Gizmo related Windows Service name to stop the service:
    • SC STOP
    • example:  SC STOP RabbitMQ
  4. Repeat the SC STOP command for each notated GSX Gizmo related Windows Services.

Clean GSX Gizmo related program folders:

      1. Navigate to the \Program Files(x86)\ directory.
