NVIDIA driver minimum requirements for Quadro

[adelaidegenay]

Hi all,

I'm making a Unity project using Asus 3D Vision monitor. This old NVIDIA product has long been deprecated and requires to install an older graphic card driver in order to work. For this reason, I installed the driver version 412.40 for my Quadro K6000 NVIDIA card and was able to render 3D stereo test scenes in Unity. But this downgrade had the consequence of stopping my Leap Motion from working. The SDK version installed was Orion 4.0.0. I tried replacing it with the v2 version, but I get the following message:

"It appears you have not installed any proprietary graphics driver from NVIDIA, AMD, or Intel. Please download and install the appropriate driver for your graphics hardware, then click Retry to continue installation. If you skip this step, the Leap Motion Orientation and Airspace applications may default to the built-in Windows driver and not run properly."

It seems that the old NVIDIA driver I installed isn't appropriate for v2 either. I could not find the minimum driver requirements online. Where can I find that ? My configuration is the following :

Windows 10, architecture x64
Intel Xeon E5-2680 v2 processor
NVIDIA Quadro K6000, driver vers. 412.40 
DirectX 12.0
32 GB RAM
ASUS VG236 3D Vision Display

Thanks in advance,
AG

Hi,

Thanks for the fast answer. You aimed right, running dpinst64.exe did the job eventhough one driver couldn't be installed when running this program.

Cheers, have a great day !

Hello again,

I've come back with another issue: when I select x86_64 architecture in Unity's build settings and run my standalone app, the Leap doesn't seem to be recognized (I get the "plug your Leap" icon).

Meanwhile, selecting an x86 architecture in the build settings doesn't cause such a problem eventhough my PC is 64-bit machine.

I'm using Unity 2019.2. I've checked my installs: the Leap Motion driver was installed with dpinst64.exe and Unity is 64 version too. Any idea on what could be wrong ?

Thanks,
AG

Which version of Leap Motion Unity assets are you using? Check if it's compatible with your Orion version.
