Setting up for CUDA Dev Work
I have started exploring parallel programming using CUDA. The latest release as of this writing is 11.8 as detailed at CUDA Toolkit 11.8 New Features Revealed | NVIDIA Technical Blog. I’m using Windows and have Visual Studio 2022 installed. I have 2 CUDA-capable devices: a Surface Book 2 with a GeForce GTX 1060 and an HP Z4 G4 Workstation with a Quadro P1000. The compute capabilities supported by these cards is at CUDA GPUs – Compute Capability.
I had previously installed the 11.1 toolkit on my Surface Book so I started by uninstalling all apps that showed up when searching for “nvidia” under “Installed Apps” except NVIDIA Graphics Driver 461 and NVIDIA Update 38.0.2.0. I then got the new installer from Installation Guide Windows :: CUDA Toolkit Documentation (nvidia.com) and installed every component presented by the installer. Note that older builds can be found at the CUDA Toolkit Archive.
You can now create a new CUDA project in Visual Studio:
Surface Book 2 CUDA Issues
Creating and running a CUDA 11.8 Runtime project on my Surface Book 2 fails with the error cudaSetDevice failed! Do you have a CUDA-capable GPU installed?addWithCuda failed! A search for using nvidia GPU on surface book 2 leads to suggestions that involve the NVIDIA Control Panel. Unfortunately, it doesn’t start on my laptop. A peek at the event viewer reveals why:

The NVIDIA Driver Symbol Server even says that it does not have PDBs (even though that’s for drivers) so this is not an optimistic path. The trimmed callstack of the main thread from the dump is shown below though. The paths to the NVIDIA binaries are C:\Program Files\WindowsApps\NVIDIACorp.NVIDIAControlPanel_8.1.962.0_x64__56jybvy8sckqj\nvcplui.exe and C:\Windows\System32\DriverStore\FileRepository\nvmsoui.inf_amd64_8fd9664c41d93f19\nvgames.dll

Launching it again errors with a dialog claiming that an NVIDIA graphics card was not detected in my system. Check out the language too…
Sure enough, device manager no long shows the GTX 1060 in the list of display adapters.
Rebooting restores the GTX 1060 but doesn’t address the crash in the NVIDIA Control Panel so I decide to move to my workstation and everything is much smoother there. The new Visual Studio CUDA project runs to completion so I turn my attention back to the CUDA installer to work on resolving the Surface Book 2 issues. The first thing I notice is that the installer is not keyboard accessible, so here’s a detour…
NVIDIA Installer Accessibility Issues
Is the NVIDIA Installer narrator-friendly? Narrator informs me that there are new natural voices available so I install them (Microsoft Aria, Guy, and Jenny).
Looks like narrator works with the installer. However, the installer cannot be used via keyboard alone due to these issues:
- You cannot TAB out of the NVIDIA software license agreement.
- Narrator doesn’t read the captions below the Express and Custom radio buttons on the Installation Options page.
- You cannot TAB into the components tree to select them via keyboard.
- Keyboard navigation works after clicking on a component but the focus goes back to the NEXT button after using ALT+TAB to switch to another program then back.
- Narrator reads the individual components, e.g. “NSight Systems, Selected” regardless of whether the checkbox is ticked or not. How does one know it’s a checkbox?
- The custom installation components columns are not resizable (Component, New Version, and Current Version). For example, what NVIDIA GeForce Experience compo…
- Why isn’t it resizable?
A general usability issue: why do all the NVIDIA components need to be uninstalled individually instead of having an option to remove everything?
Outstanding Questions
- How do we figure out which component installed the NVIDIA Control Panel? One approach is to uninstall the existing components until the control panel binary from the dump file is deleted on disk. Removing NVIDIA NSight Systems 2022.4.2 removed the
C:\Program Files\WindowsApps\NVIDIACorp.NVIDIAControlPanel_8.1.962.0_x64__56jybvy8sckqj\directory. However, installing only this component in 11.6 did not bring back the NVIDIA control panel! - The installer asks for a path to a temp directory to unpack setup file into. Could examining that folder help determine where the control panel is coming from?
- Was this installer generated by NSIS?
Resolution
I end up uninstalling all “nvidia” components on the Installed Apps page except NVIDIA Graphics Driver 461.40 then installing all components from CUDA 11.6. This finally has a working control panel!
Surprisingly, this executable is in C:\Program Files\WindowsApps\NVIDIACorp.NVIDIAControlPanel_8.1.962.0_x64__56jybvy8sckqj, the same directory as 11.8! This must not have been the buggy component! Here is the version info for the 2 NVIDIA binaries in the earlier crash dump (nvgames.dll is now in C:\Windows\System32\DriverStore\FileRepository\nvmsoui.inf_amd64_ed4d74dfae95b5e6):
Visual Studio 2022 does not have the new CUDA project option though. However, changing the paths (in the .vcxproj) for my new project created using the 11.8 tools on my VS 2022 desktop makes the program work. Looks like I need to use 11.7 instead so I uninstall all the “nvidia” components except the NVIDIA Control Panel and the NVIDIA Graphics Driver 511.23 before installing 11.7. Thankfully, 11.7 works just fine!
