The Add-on <addon-name> failed to install: Failed to update the database. Click here for more information.
I have a number of extensions or panels that generate this error message each time I boot Photoshop CC 2014.
The add-ons don't show up in Extension Manager. They are not installed. I want them to stop trying to install.
I've uninstalled and reinstalled both Extension Manager and Photoshop.
I just ran into this problem with a extension for Illustrator. I also would like an answer to this.
I can install a new add-on (for lightroom) and it shows up in extension manager. However it doesn't show up in lightroom after restart app and reboot.
Click "Remove" button for the add-on and it disappears from extension manager but I get the "Failed to update the database" error.
Subsequently I cannot add that Add-on again. (Extension manager doesn't see it again after initial install.)
