Problem Installing UXP plugins on Windows 10

Photoshop UXP Plugin API
,
1

I have a client with a Windows 10. He’s trying to install my .CCX file but:

  • Double click, the mouse loads for a second and nothing happens.
  • Right click and open with → UnifiedExtensionManager, nothing happens.
  • Manual installation on paths:
    C:\Program Files\Common Files\Adobe\UXP\Plugins\External
    C:\Users\user\AppData\Roaming\Adobe\UXP\Plugins\External

Nothing loaded into Photoshop neither Creative Cloud. There’s no error message no feedback to the client or to use on how to solve this. I know how frustrating is for the client and it is more for us.

If someone have had this issue and solved, could you help me?

Thank you!
