I have a custom panel but I am unable to install it in version 13.01 of photoshop.
I have tried to contact the person that sent me the panel but I am not getting any response.
Having read various reports about this, i was wondering if Adobe are aware of the issue and if they are planning a fix for it.
In the meantime does anyone know how I can get the contents of the ZXP file extracted or any other way of getting the panel re-instated
If you have gpc file of your panel, you can export the extension again with Configurator 3.1.1. There is a compatibility issue.
In your case, you only have the exported extension. You can send your extension to email@example.com, I can help you to solve the compatibility issue of your panel.
