After upgrading as prompted, Roon won’t start. Tried uninstalling completely and re-installing using the latest installer, but still does not launch. Even tried uninstalling and re-installing the previous 1.7 version that worked, but even though the Roon loading window appears, even that previous version won’t launch now. Tried to re-install 1.8, won’t launch. Please help

Hi @Dobbo_Wong

What kind of GPU does your device use? Can you try uninstalling and reinstalling the GPU drivers?

If there is no change after that please use the directions found here and send us over a set of logs using a shared Dropbox link.

I uninstalled the and reinstalled the drivers and Roon 1.8 started to work , just once, until the next reboot when it stopped working again and was I unable to launch it, just like before.

The logs are uploaded to OneDrive here

The GPU is Intel HD Graphics 4000. The machine is a Microsoft Surface Pro (1st generation). I use this as my core. Microsoft have their own version of the Intel drivers (10.18.10.4252). I even tried installing the latest driver version from Intel, but got the following error

" A customized computer manufacturer driver is installed on your computer. The Intel Driver & Support Assistant is not able to update the driver. Installing a generic Intel driver instead of the customized computer manufacturer driver may cause technical issues. Contact Microsoft for the latest driver for your computer."

So it seems the only way to get a updated drivers is via Windows update, and this driver version does not work with Roon 1.8. The strange part is that Roon 1.8 did launch once after the first update of the drivers but now won’t launch anymore. Any ideas?

Update: I managed to get the latest Intel HD Graphics 4000 Driver 10.18.10.516 (directly downloaded from Intel) to install by manually uninstalling the 10.18.10.4252 driver (available from windows updates) from device manager, then without re-booting install the latest 10.18.10.516 Intel version from via the driver installer .exe. Now, even after a reboot the latest 10.18.10.516 stays installed and now Roon 1.8 starts
