The SmugMug plugin has been updated in ACDSee 2026 to support the new SmugMug API. To update the plugin in ACDSee 2025 versions, follow these steps:

  1. Download the attached plugin file.
  2. If ACDSee 2025 or ACDSee Gemstone is currently running, close it.
  3. Open Windows Explorer and navigate to the plugin folder for your version of ACDSee 2025. The default plugin folder locations are:
  • For ACDSee Ultimate 2025:
    C:\Program Files\ACD Systems\ACDSee Ultimate\18.0\PlugIns
  • For ACDSee Professional 2025:
    C:\Program Files\ACD Systems\ACDSee Pro\18.0\PlugIns
  • For ACDSee Home 2025:
    C:\Program Files\ACD Systems\ACDSee Home\28.0\PlugIns
  1. Back up the existing "CX_SmugMug.apl" file by renaming it—for example, to "CX_SmugMug.apl-back".
  2. While still in the plugin folder, copy and paste the files you downloaded in step 1.
  3. When prompted, confirm that you want to add or replace the files.
  4. Launch ACDSee and log in to the SmugMug site. You can now transfer files to SmugMug directly within ACDSee.
