Upgrade

I am trying to install the new upgrade but I get a "castastrophic failure" message in the Wizard and then it closes down. What do I do?
thank you

Maybe you try uninstall the old version and then install again.

Please see if any of the suggestions here help: Problems installing Opus.

Re uninstalling, not that it will wipe your config, so if you want to try that as suggested above, it's a good idea to back it up first. Details here on how to locate the config folder to back it up manually, if Opus can't start. (If the old version is still working, you can use Settings -> Backup & Restore.)
