Deployment Method: Individual Install, Upgrade, & Uninstall

To install GNU Prolog (MSVC), run the following command from the command line or from PowerShell:


To upgrade GNU Prolog (MSVC), run the following command from the command line or from PowerShell:


To uninstall GNU Prolog (MSVC), run the following command from the command line or from PowerShell:


Deployment Method:

📝 NOTE: This applies to both open source and commercial editions of Chocolatey.

1. Enter Your Internal Repository Url

(this should look similar to

2. Setup Your Environment

1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

2. Get the package into your environment

  • Open Source or Commercial:
    • Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
    • You can also just download the package and push it to a repository Download

3. Copy Your Script

choco upgrade gprolog-msvc -y --source="'INTERNAL REPO URL'" [other options]

See options you can pass to upgrade.

See best practices for scripting.

Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.

If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:

choco upgrade gprolog-msvc -y --source="'INTERNAL REPO URL'" 

Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)
if ($validExitCodes -contains $exitCode) {
  Exit 0

Exit $exitCode

GNU Prolog

GNU Prolog is a free Prolog compiler with constraint solving over finite domains developed by Daniel Diaz.

GNU Prolog accepts Prolog+constraint programs and produces native binaries (like gcc does from a C source). The obtained executable is then stand-alone. The size of this executable can be quite small since GNU Prolog can avoid to link the code of most unused built-in predicates. The performances of GNU Prolog are very encouraging (comparable to commercial systems).

Beside the native-code compilation, GNU Prolog offers a classical interactive interpreter (top-level) with a debugger.

The Prolog part conforms to the ISO standard for Prolog with many extensions very useful in practice (global variables, OS interface, sockets,...).

GNU Prolog also includes an efficient constraint solver over Finite Domains (FD). This opens contraint logic programming to the user combining the power of constraint programming to the declarativity of logic programming.


  • /InstallationPath: - where to install the binaries
    • Default value: "$env:SystemDrive\GNU-Prolog"
  • /CreateDesktopIcon - creates a desktop icon
    • Not created by default
  • /AssocPl - associates GNU Prolog as the default app for *.pl files
    • Not associated by default
  • /AssocPro - associates GNU Prolog as the default app for *.pro files
    • Not associated by default
  • /AssocProlog - associates GNU Prolog as the default app for *.prolog files
    • Not associated by default


  • Install into D:\gprolog directory
    choco install gprolog-msvc --params "/InstallationPath:"D:\gprolog""
  • Install with all file associations
    choco install gprolog-msvc --params "/AssocPl /AssocPro /AssocProlog"
  • Install and create desktop icon
    choco install gprolog-msvc --params "/CreateDesktopIcon"

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).
