Adobe Get Started

This document explains how to install the FlexLink plugin into your Adobe applications to use Flexbar’s Adobe integration features.

Since the FlexLink plugin is built using the legacy Adobe CEP framework, it may not run properly on Apple Silicon devices. We’re actively working on a new UXP version to replace it.

Enable Developer Mode

First, update the following Adobe setting to prevent your host application (Photoshop, InDesign, etc.) from showing warnings about unsigned extensions. Refer to the HTML Extension Cookbook section on Debugging Unsigned Extensions for more details:

Windows: Open regedit and navigate to HKEY_CURRENT_USER/Software/Adobe/CSXS.<X>. Add a new string value named PlayerDebugMode and set it to 1.

⚠️ Make sure there are no extra spaces in PlayerDebugMode.

Mac: Open Terminal and run: defaults write com.adobe.CSXS.12 PlayerDebugMode 1 defaults write com.adobe.CSXS.12 AllowUnsignedExtensions -bool true

⚠️ CSXS.<VERSION> needs to be adjusted according to your Adobe software version, version 12 for 2025, version 11 for 2024

On macOS, Terminal is located at Applications > Utilities > Terminal.

Verify Installation

After launching your Adobe application, go to Window > Extensions and look for Flex Link.

You’re all set! Flexbar’s Adobe integration is now ready to use.
