"No graphic card detected!" with GTX 780, no CUDA - atomicthumbs - 16.07.2017
Version: Windows 64-bit, 2017.05.06.1; Nvidia driver is updated.
"No graphic card detected!" dialog pops up on startup; NVEnc doesn't show up in Video Handling menu.
Step-by-step guide: have Nvidia GTX 780 and open Hybrid.
Debug output attached.
RE: "No graphic card detected!" with GTX 780, no CUDA - Selur - 17.07.2017
Okay, that is a new one.
On Windows Hybrid checks all entries of the Windows Registry under "HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Video" for 'Device Description' and only reports "No graphic card detected!" when it can't find any such entry.
-> Does your Windows Registry contain any such entries? Are you running some anti-virus software or similar that is hindering Hybrid from reading those entries?
(Side note: Don't run Hybrid with Administrator rights! Reading the registry should not require additional rights.)

Here's what's under that Video key:

Of note, the second Video key (highlighted) has a value named DeviceDesc with the data:
@oem66.inf,%nvidia_dev.1004%;NVIDIA GeForce GTX 780There are no values directly under HKLM\SYSTEM\CurrentControlSet\Control\Video.
I'm running Windows Insider build 16241, if that helps.

Hybrid searches all keys under "HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Video" for 'Device Description'.

no such key exists on my computer anywhere under the video path.
no idea why not, but there are a number of other keys that seem to contain similar info. checking for others might help; I suspect that other people have this issue, as I haven't done anything special or out of the ordinary, but perhaps they just don't use NVenc.
I just installed hybrid 2017.5.6.1 on my laptop, which has Intel integrated graphics, and it's having the exact same issue. I know Quicksync encode and decode works with other software.
RE: "No graphic card detected!" with GTX 780, no CUDA - Selur - 31.07.2017
Did you install the official drivers from NVIDIA/Intel (not just the drivers that come with Windows) ?
RE: "No graphic card detected!" with GTX 780, no CUDA - atomicthumbs - 31.07.2017
Yes, in both cases. Given that both computers are running the same Windows Insider fast ring build, I suspect it's an issue with that; if this is the case, it will affect all users once the next major Windows update is released.
RE: "No graphic card detected!" with GTX 780, no CUDA - Selur - 02.08.2017
Once that is the case I will look into it, seems strange since normally the drivers write those settings not Windows itself.

Heyo,
For whatever it's worth I have the same issue.
- Windows Build 16257
- NVIDIA GTX 1080, Driver 384.94
I looked at those keys and found several with DeviceDesc, but none with DeviceDescription (or were you just generalizing?)
If it helps I'm happy to export my Reg entries
RE: "No graphic card detected!" with GTX 780, no CUDA - Selur - 07.08.2017
No, I'm not generalizing. Hybrid looks for 'Device Description' entries below 'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video'.
An export of the 'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video' might be worth a look.
