The RoonServer works fine, but, the Roon client, when I try to open it close (crash) itself after 2 or 3 seconds.
If I reinstall it, it works again, but, after a couple of days, same issue, it crashes at the start (it opens then crash), then I need to reinstall the latest build and it works for some days.
Please use the directions found here and send us over a set of logs using a shared Dropbox link (or any other file sharing service) and we’ll take a look at what’s happening.
Can you also give us a bit more information about your library? About how many tracks total do you have? Where are they stored?
I would go to the graphics card manufacturer site and load the latest drivers, not Windows update.
Windows update often leads terrible driver versions.
