I have just updated to Photoshop CC 2015 and, as seems to happen with most major Photoshop updates, my custom built extension panel stopped working.

Custom Photoshop 2015 Panel
It’s not a particularly complicated panel but it has links to a few commands / actions that I use regularly & I hate not having them available. You never know, one day I may even get around to extending it’s functionality.
Luckily this time it’s not as serious as having to convert all of the scripts from ActionScript to HTML5 (don’t even get me started on that!).
in fact it was simply a matter of updating the target versions in the tag of the manifest.xml file, re-compiling the code and adding it back in with Adobe Extension Manager CC.
Here’s what the old Tag looked like:
<HostList>
<Host Name=”PHSP” Version=”[15.0,15.9]” />
<Host Name=”PHXS” Version=”[15.0,15.9]” />
</HostList>
and here’s how it looks now
<HostList>
<Host Name=”PHSP” Version=”[15.0,16.9]” />
<Host Name=”PHXS” Version=”[15.0,16.9]” />
</HostList>
So by simply updating the upper range of the versions from 15.9 to 16.9 I was able to reinstall my custom panel by running Adobe’s Extension Manager from the “Manage Extensions” option in the “Help” menu.
Now, if only ON1 would get their Perfect Photo Suite 9.5 panel working in Photoshop CC 2015 everything would be back to normal 🙂
Update 23/06/2015:
As Lee Haneman mentioned below, another alternative is to remove the upper version restriction in the <HostList> and it should remain valid for all future versions (not allowing for any further changes made to Photoshop by Adobe of course 🙂 ).
Your tag would now look like this:
<HostList>
<Host Name=”PHSP” Version=”[14.0]” />
<Host Name=”PHXS” Version=”[14.0]” />
</HostList>
Update 22/06/2015:
- Apparently Adobe have announced that Adobe Extension Manager CC will no longer be updated or maintained but it does still work in Photoshop 2015 and is still available for download. Download Page for Adobe Extension Manager CC (Windows & Mac).
- You can also manage extensions from the command line so I assume, at least in the short-term, it will still be possible for developers (such as ON1) to automatically install add-on panels, in fact a command line only version is also available for Windows & Mac.
- If you are interested in ON1’s progress on this front the check out their blog post Adobe® CC 2015 & ON1 – What You Need to Know.
If this all sounds like a load of geek talk then totally ignore the above and focus on the beautiful sunset from Quinns Rocks below …
