Installed new version 5.0.1 and now none of the plug-ins for Affinity Photo will launch. Configuration is still the same but in Affinity Photo when I go to Menu > Filters > plug-ins > Nik Collection I still see the Nik plug-ins listed but none of them will launch when I click on a plug-in to launch it. Nothing happens at all.
The Nik Collection standalone executable files for 5.0.1 work ok, it’s just the plug-ins for Affinity Photo that fail to do anything now.
So I uninstalled 5.0.1 and reinstalled 5.0.0 and all is fine again.
I had the same problem, but it seems the issue was with upgrade going wrong. Just like you did, I uninstalled 5.0.1 and then installed 5.0.1 again (not 5.0.0) - and plug-ins in Affinity started working!
Thank you for that. I just now tried what you did, uninstalled 5.0.0 and reinstalled 5.0.1 but I still have the same problem. 5.0.1 plug-ins simply won’t start.
So I uninstalled 5.0.1 again and reinstalled 5.0.0 which is at least useable.
Color Efex Pro is the plug-in I use the most by far and that’s the only one I’ve verified the problem with.
I still think that something goes wrong with your installation of 5.0.1, I suggest to look at the contents of directories where you install to verify that files are there.
