What is nvscpcap64.dll?

When I load Windows 10, a pop-up says:

Run dll

Problem starting C:\Windows\system32\nvspcap64.dll
The specified module cannot be found.

If I close the window, everything proceeds normally.

It's the library file for the nVidia Capture Server Proxy

You'll find a good copy of it in your unpacked installer package

NVIDIA\DisplayDriver\<Version number>\<Windows Version>\International\ShadowPlay\nvspcap64.dll

You can copy that to your C:\Windows\System32 folder if you want the error to vanish (or you want to actually use the video capture feature for your driver!)

Otherwise it's just an annoying message where the nVidia installer forgets that it needs specific user permissions to drop the file into the correct location under some circumstances.

Until nVidia fix their bug look forward to seeing the error everytime you upgrade your graphics driver through their Geforce Experience application!

I do not have a Windows 10 disk, as the computer came with the OS already installed.   Is the installer package somewhere on the C drive?
Yes, it's the nVidia graphics installer try C:\NVIDIA\DisplayDriver (it's not part of Windows 10)
I tried to copy the file to the System 32 folder, but I cannot replace it as it is open in another program.
Then the file is already present in System32

Try uninstalling GeForce Experience restarting and then reinstall it.
I uninstalled GeForce Experience and tried to reinstall it, but installation failed.   In any case, the pop-up has disappeared.   What is GeForce experience used for?
