Roon Core won't open

[Jesse_Webber]

Core Machine (Operating system/System info/Roon build number)
Windows 10, latest build (can’t open it to verify, but it did update several weeks ago)

Network Details (Including networking gear model/manufacturer and if on WiFi/Ethernet)
Wifi (this isn’t the issue)

Audio Devices (Specify what device you’re using and its connection type - USB/HDMI/etc.)
Multiple RPi, also not the issue

Description Of Issue
I had Roon up and running during my free trial. All was good, so I let it charge me. 10 days later Roon updated to the newest build and then would not open on my Windows 10 desktop. I literally closed it to update it and then it wouldn’t open again. I double click the icon, get the spinning wheel, and then nothing happens. Remotes say “waiting for remote core”. Restarted my machine multiples times, removed and re-installed Roon, nothing worked. 2 days later it just was able to open again.

Fast forward to this week… had a power outage so I had to restart my machine. Roon won’t open exactly like before. Multiple restarts and days of waiting do not fix it. I’ve searched here and am not finding solutions to this exact issue.

Sorry for the trouble here, @Jesse_Webber!

Please try each of these steps, and try to launch Roon after each.

1. Reinstall the Roon app
2. Disable the devices firewall
   1. If this helps, please enter an exception in the firewall for Roon and RAATServer
3. Uninstall and reinstall the graphics drivers directly from the manufacturer’s website
   1. Don’t use Window’s automatic driver updates for this — We’ve seen this cause issues in the past
4. Download .NET Framework and reinstall it

Next Steps

If none of the above helps, please use these instructions to send us Roon logs from the device.

We’ll also want to take a look at Event Viewer logs, which give some insight into errors being reported by the OS — Please send those as well:

1. Press Win + R and type eventvwr.msc
2. Press OK – this should open Event Viewer window
3. From the left sidebar go to Windows Logs > Application
4. Right click on the Application subsection and pick Filter Current Log… from the context menu
5. 
6. On the Filter tab for the Logged section pick a parameter Last 30 days and press OK
7. 
8. Right click on the Application subsection again and pick Save filtered log file as… from the context menu
9. Enter the log file name, for e.g. Roon_USERNAME , and press Save
