I have install the support package for matlab r2014b version. But the adaptor still not installed. The matlab told me there is no Image Acquisition adaptors found. How could I fix this?

I have installed OS Generic Video on my Linux computer and I have the same problems. I have googled this problem for a while now, and I can't find a solution to the problem. Any thoughts?

I am having this problem too in R2015b 32 bit. I have the Trial version of the Image Acquisition Toolbox, as well as the full version of Matlab and the Image Processing Toolbox. I installed my camera manufacturer's hardware twice using 'Support Package Installer' without any errors and restarted Matlab after, and still got the following output from imaqhwinfo,
InstalledAdaptors: {}
MATLABVersion: '8.6 (R2015b)'
ToolboxName: 'Image Acquisition Toolbox'
ToolboxVersion: '4.10 (R2015b)'
Here is info about the OS Generic Video Interface. When I tried to install it I got,
Warning: Unable to save path to "C:\Program Files (x86)\MATLAB\R2015b\toolbox\local\pathdef.m".
MATLAB may not have write access to the folder. Possible fix:
1) Use SAVEPATH with an input argument to save path to a temporary file
2) Restart MATLAB as Administrator
3) Load path from temporary file
4) Call SAVEPATH
> In hwconnectinstaller.RegistryUtils.savePath
In hwconnectinstaller.PackageInstaller/install
In hwconnectinstaller.PackageInstaller/installRecursiveImp
In hwconnectinstaller.PackageInstaller/installRecursive
In hwconnectinstaller.internal.executeConfirm>installFromFolder
In hwconnectinstaller.internal.executeConfirm>performThreadedDownload
In hwconnectinstaller.internal.executeConfirm>installFromInternet
In hwconnectinstaller.internal.executeConfirm>installWorkflow
In hwconnectinstaller.internal.executeConfirm
In hwconnectinstaller.Step/next
So I switched to running Matlab as Administrator, installed the generic video interface, saved the path with savepath, and the generic video interface appeared in imaqhwinfo. I then tried to install my camera manufacturer's hardware but it still did not appear in imaqhwinfo. So, I put in a Service Request and the person from MathWorks said that I would need to have first manually downloaded the drivers for my camera manufacturer before running the Support Package Installer. [I am not able to confirm because I can no longer access the Image Acquisition Toolbox, but am mentioning this in case it helps someone].

When I bought the non-trial version of the Image Acquisition Toolbox, the problem disappeared.

I had same the problem, this worked for me: Go to Home tab >> Get Hardware Support Package under Add-Ons from Environment section >> choose Install from Internet and select OS Generic Video Interface from supported drivers >> Next >> I accept and Next >> wait for installation finished. There you go. type 'imaqhwinfo' in Command Window and see 'winvideo' is added

That didn't seem to work for John Porter who had installed that package. There is a separate hardware support package for USB webcams. If that also doesn't work, he should call tech support.

The OS Generic works with the gstreamer system libraries on linux. MATLAB supports gstreamer 1.0 for releases R2017a and later, and gstreamer 0.10 for other releases. You can get the version of gstreamer on your system by running this on your linux terminal:
dpkg -l libgst* | grep ^i
