Hello,
As of yesterday my previously trouble free installation of build 18.0.195 will no longer successfully launch the Theater View GUI. I receive the "Error starting Direct3D engine (error creating Direct3D device (0x8876086C)) notification discussed in a few threads over the years. I installed no updates of any kind prior to receiving the error. That said, the core problem lies within my Win7 x64 OS, not JRiver. I verified this via a complete uninstall, reboot and reinstall of JRiver. A clean install generates the same error message when attempting to launch Theater View.
I have been unable to track down the culprit for this error. So far, I've:
Verified the expected D3Dxx.dll files reside in the System32 directory.
Verified there are no reported DirectX errors via the dxdiag tool.
Reinstalled DirectX11.
Reinstalled the ATI Catalyst video driver that I had been using with success.
Updated the ATI driver to the latest build.
I'm open to additional suggestions.
Thanks, folks.
Brian
