Deployment Method:


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

1. Enter Your Internal Repository Url

(this should look similar to https://community.chocolatey.org/api/v2/)

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 https://community.chocolatey.org/api/v2/. 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 cupscale -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 cupscale -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

Image Upscaling GUI based on ESRGAN


Based around xinntao's ESRGAN implemented via Joey's Fork.

AMD/Intel GPU compatibility is possible thanks to BlueAmulet's esrgan-ncnn-vulkan based on nihui's realsr-ncnn-vulkan running on Tencent's ncnn framework, as well as xinntao's Real-ESRGAN.

Supported AI Backends:

  • Nvidia CUDA (Recommended)
  • Vulkan (Works on any modern GPU, but is slower and takes a long time start up)
  • CPU (Works without GPU, but is very slow)


  • CUDA, Vulkan/NCNN or CPU supported, with included model converter for NCNN
  • On-the-fly Model Interpolation
  • Model Chaining (Run images through multiple models at once)
  • Batch Upscaling (Load a directory or multiple single images)
  • Automatic Image tiling/merging to avoid running out of VRAM
  • Pre-Processing: Optionally downscale images before upscaling
  • Post-Processing: Automatically resize after upscaling
  • Compatible with PNG, JPEG, BMP, WEBP, TGA, DDS images
  • Load image straight out of the clipboard (no need to download images from web)
  • Create various types of comparisons (Side-By-Side, 50/50, and before/after animations as GIF or MP4)

To change the installation directory use the parameter --params "/InstallDir:C:\your\install\path". Temporary files are stored in the installation directory by default, which is why you shouldn’t install the application in protected locations like Program Files.

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).

Chocolatey Pro provides runtime protection from possible malware.
