Hello everyone,
I'm a developer working on a UXP plugin for Premiere Pro and I've run into a critical environment issue that I can't solve. My UXP Developer Tool is unable to detect my stable installation of Premiere Pro 2025. I am hoping someone in the community has seen this before and can offer some advice.
My Environment:
Host Application: Adobe Premiere Pro 2025 (Latest stable version, not Beta)
Development Tool: Adobe UXP Developer Tool (Latest version)
Operating System: Windows
The Problem: When I launch the UXP Developer Tool, the "Select an Application" dropdown only shows "Premiere Pro Beta," which is an old version that has been uninstalled. It does not detect my current, stable installation of Premiere Pro 2025.
When I try to load any plugin (including official Adobe samples), it fails with the error message: Plugin Load Failed. No applications are connected to the service.
Expected Behavior: The UXP Developer Tool should list my stable "Premiere Pro 2025" installation, allowing me to load and debug my plugins.
Actual Behavior: The tool only shows the uninstalled Beta version with a warning icon. No connection to the running, stable Premiere Pro application can be made.
Exhaustive Troubleshooting Steps Already Taken:
We have tried to solve this for hours and have performed the following actions without success:
Standard Reload: Used the "Reload" function in the UXP Developer Tool and restarted the panel in Premiere Pro.
Clean Reinstallation: Performed a complete and clean reinstallation of all Adobe software (Premiere Pro, Creative Cloud, UXP Developer Tool) using the official Adobe CC Cleaner Tool.
Manual Cache Clearing: Manually deleted all known Adobe and UXP cache folders from %APPDATA%, AppData\Local, and ProgramData.
Manual Registry Cleaning: Manually searched the entire Windows Registry for any keys related to "Premiere Pro Beta" and found none.
Manual Registry Creation: Manually created the necessary keys in HKEY_CURRENT_USER\Software\Adobe\UXP\Developer\Hosts\PPRO to point directly to the stable Adobe Premiere Pro.exe. This had no effect.
Security Software: Temporarily disabled both Windows Defender Firewall and all third-party antivirus software.
Administrator Privileges: Ran both Premiere Pro and the UXP Developer Tool as an Administrator.
Official Sample Test: Confirmed that the official Adobe hello-world UXP sample for Premiere Pro fails in the exact same way. This proves the issue is not with my own code.
Given all of the above, the problem seems to be a fundamental issue with the Adobe background services (like the IPC broker) or application registration on this specific machine that has somehow survived a full clean reinstallation.
Has anyone encountered such a persistent environment issue before? Are there any deeper-level diagnostic logs I can check or advanced steps I can take to force the UXP Developer Tool to recognize my Premiere Pro installation?
Thank you in advance for any help you can provide.
