I think, that the updater was not downloaded in the Temp-Folder an therefore the update can not run.
The exe file is not in the temp folder.

Thanks!

Hi, as it’s the weekend now and Roon support may not be able to get back to you until next week.

May I suggest a workaround; download the latest version of Roon from their website.
Then with the Roon Core stopped, perform a manual installation. Don’t delete anything just install it over the top of your current install and then start-up Roon once more.

Hi Carl,

I had the same idea reinstalling Roon, which worked out very well. Thanks!
