I used webcam in Matlab 2014b to acquire images. But today when I used webcam in matlab script, it shows an error
Error using webcam (line 13) MATLAB Support Package for Webcams has not been installed. Open Support Package Installer to install the Webcam Support Package._
I already installed Webcam Support Package and its location is C:\MATLAB\SupportPackages\R2014b\usbwebcams.
To change my support directory I used matlabshared.supportpkg.getSupportPackageRoot but it shows error
Undefined variable "matlabshared" or class "matlabshared.supportpkg.getSupportPackageRoot".
When I tried to reinstall webcam support package, it shows error that already you have R2014b\usbwebcams first make empty that. I have many other support packages and so don't want to reinstall every package again. How should I solve this problem?

You appear to have a corrupted list of add-ons. In R2014b, the only way to fix that was to uninstall them all, delete the add-ons directory, and re-install the ones you wanted.

I have the same issue with genicam drivers for usb3 cameras in R2017a. Even after installing them imaqhwinfo shows no installed adaptors. I uninstalled the package from add-on explorer and reinstalled multiple times, in vain. The same drivers work in R2018b on the same pc. They even work fine in R2017a on another PC with exact same configuration. Any ideas what more to try?
