Solution to "category installer refuse to install or update this device"

When installing the camera, "unable to install device: Category installation" is displayed after the driver is installed.ProgramRefuse to install or update this device ". This is a problem where the driver cannot be installed. It is not a problem with the camera, nor with the driver. It is a system problem that is aborted during installation.

To solve this problem:

First, uninstall the installed error camera, uninstall the driver, and restart the computer.

Second, disable firewall, anti-virus software, and other software with protection functions.

The above two steps are only for the purpose of preventing unexpected situations, or directly start from step 3.

Again: Modify the RegistryHKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ runonce

(Pay attention to backup before modification), right-click on the key value (that is, the folder on the left tree menu)---Permission---Add a management user (the management user on the sub-host is empty, so the Super User and personal user are added, that is, the user who created the system by himself)---Set to full control. This operation may fail. You need permission inheritance. Right-click the key value.---Permission----Advanced---Select the options for Example---OK.

Finally, install the driver, connect to the camera, and select automatic installation,OK.

The above method has been tested and installed successfully.
