We have identified that sometimes download manager may not have finished downloading updates despite the GUI showing the update is ready or is stuck on a loading screen. This may cause an error message of ‘X plugin failed to install’ or not allow you to install at all.
Our software team are working in a fix, in the meantime please try the following;
- Wait approximately 5 minutes for the application download to finish in the background, even though system displays “Loading…”
- Close and re-open the Download Manager GUI.
We don’t recommend you reinstall, since this might just keep showing the same issue.
If Download Manager still fails to install the plug-ins you can find the individual installers here: SSL and Harrison Plug-in Downloads
In Mac we have had some success with doing the following:
Navigate to library folder / application support / SSL Download manager - and delete that folder. Then deleted the application from the applications folder. Redownload and install download manager and check for functionality.
