Description Of Issue
I have very recently upgraded this machine and another (very different) PC from Windows 10 version 1809 to 1903 (with current July updates). Now when I try to run the current Roon or the current Roon Server installation files, I get an immediate pop up for RoonInstaller64.exe (or RoonServerInstaller64.exe) - Application Error - The application was unable to start correctly (0xc000007b).
This has happened on two different PCs, both with new (separate) downloads from your site and with an older download of the Roon installer that had previously been used to install Roon to the Lenovo successfully in January while it was running Windows version 1809.
This strongly suggests to me that Windows 10 version 1903 (with current July updates) has introduced an incompatibility with the current Roon installers, which previously worked on Windows version 1809.
Obviously I’m not really in a position to diagnose this further. The installers fail before any logs are created, and the Lenovo is a very clean installation, but with the Windows 10 1809 to 1903 feature update installed.
