I have three systems. Two desktops and one laptop. Two with Mint 19 and one with Ubuntu 18.10 and all three of them fail during the installation. They all fail in exactly the same way. So, I am guessing something is missing from the install. All three of these were on new bottles for testing purposes. The error seems to be a failure with loading XAudio2_0.dll. Has anyone else found a fix for this issue? I saw a post that mentioned that mscoree.dll is a requirement. So, I installed .Net 4 (which brings along .Net 2 as well). That didn't make any difference. The error is the same. For those who are interested, the error message that is generated in the DXError.log is below. Let me know if anyone has any ideas. I'm up for trying anything.
