Tick the box and use the hook to remove all others. And play the CD, don't install the driver from the CD. Let the system automatically search (WWW. PC84 1。 COM)。 . So that the installation can be successful.

The reason why the driver is not easy to install or difficult to install during the update process. At present, there is a cloned operating system on the market, which integrates the old version of ZTE Micro and is driven by WHQL. When the user installs a new camera or updates the latest driver, the camera can't work normally.

Method 1: Automatic uninstall method

Step 1: Click Uninstall the corresponding driver in the Start menu. (It is possible that the uninstallation function has been damaged, and it can be uninstalled by installing a new driver. The system will uninstall the old driver first, and the purpose can be achieved. )

Step 2: Before installing the new driver, select the following corresponding executable file in the attachment: FOR_XP_ME_98. EXE for Windows XP/ME/98 FOR_Win2K。 For Windows 2000.

(Note: this tool requires that the default path of the system is disk C. If an error dialog box appears under the Windows ME/98 operating system, it means that the system is clean and the tool will not harm the installed drivers. )

The third step is to install a new driver.

Method 2: Manual unloading method

Step 1: In My Computer-Tools-Folder Options-View, select Hide Files and Folders as? Show all files and folders? . Then go to the folder C:\Windows\inf and save all OEM files (such as oem0.inf, oem0.pnf; oem 1.inf，oem 1.pnf？ Cut and transfer to another directory to save or manually delete the oem file corresponding to the camera.

Step 2: After completing the above steps, plug in the USB camera. At this time, the computer will find new hardware and pop up the information of installing drivers. Select Cancel, then right-click my computer and select Properties. In the pop-up system properties interface, enter System Properties-Hardware-Device Manager, and press the right mouse button to uninstall the PC camera with exclamation point.

Step 3: Unplug the camera and start installing new drivers.

The solution to that second phenomenon is:

Step 1: By default, cloning the operating system saves the camera driver in the folder C: \ Windows \ driver \ camera \ 301p. When you click the new camera driver CD to install it, you will not be prompted that there is already a camera driver. Uninstall this driver, please find this folder and delete it;

The second step is to install a new camera driver, then plug in the camera to load the hardware, and restart the computer after the installation is completed, so that it can be used normally;

Step 3, click the new CD to install the latest driver without repeating the above two steps. After the camera is plugged in, the system detects the new hardware and automatically finishes loading the hardware driver.

The fourth step, enter the device manager, you can see that the image processing device has been successfully installed, but when it is opened? AMCAP？ When previewing a picture, there will be no preview, white screen and black screen;

Step 5, put the right mouse button on? Vimicro USB PC camera (ZC030 1PL)? Update the driver and select? Install from a list or as a location;

Win7 camera doesn't work

The camera can be used normally under Windows XP system, but it can't be used after changing to Windows 7 system. The camera itself is an unmanned product. Although it can't be used, you can find the equipment in the system. What is the reason?

Driver-free camera, its chip has integrated the driver of Windows. If your camera does not integrate the Windows 7 driver, your camera will not work. Windows 2000/XP/Vista drivers cannot be used in Windows 7. The solution is as follows:

Ask the manufacturer for the latest camera chip firmware. If the latest firmware program supports Windows 7, you only need to upgrade the camera chip firmware again.

The computer camera is broken.

There may be two reasons for this phenomenon, one is that your camera driver is not installed correctly, and the other is that your USB interface has hardware failure. At present, most camera drivers are built into the operating systems of Windows XP/Vista and Windows 7. However, due to the rapid development of product technology, some new cameras may have to reinstall their own drivers before they can be used normally. So I suggest you install the driver that comes with the camera set you bought first and see if you can solve the problem.

If there is nothing wrong with the driver, there may be something wrong with the USB interface. First, you connect the camera to a USB slot to see if it can be used normally. If it can be used in other slots, there is something wrong with your original USB slot. If it still doesn't work, there may be something wrong with the USB interface of your camera. It is recommended to send it for repair or replacement.
