打印机安装驱动程序被拒绝

When you try to install a printer driver, you may get the error "Access denied (code 700)" if you don't have administrator rights on Windows or are not logged in as an administrator. The error message can also be caused if the printer's driver is not compatible with the version of Windows you have or if the driver is not digitally signed. In this article, we will discuss some methods you can use to fix this issue.

1. Check your user profile: This is the most common cause of Access denied (code 700) when trying to install a printer driver. Make sure you are logged in as an administrator or have administrator rights to install the printer driver. To check your user profile, go to the Control Panel and click on User Accounts and Family Safety. Select Manage User Accounts and then select your user account. Make sure you have administrator privileges for the account.

2. Download the correct driver: Sometimes the error can happen if the driver you are trying to install is not compatible with the version of Windows you are using. Make sure you download the correct driver from the manufacturer’s website and then try to install it.

3. Enable the driver signature enforcement: A driver must be digitally signed in order to be installed on Windows. This is known as driver signature enforcement. To enable this feature, you will need to open the Command Prompt as an administrator. To do this, go to Start, type cmd, right-click on the Command Prompt icon, and select “Run as administrator”. Then type “bcdedit -set TESTSIGNING ON” and press Enter. Restart the computer and try to install the printer driver again.

4. Turn off User Account Control: The User Account Control (UAC) is a security feature in Windows that can help protect your computer from malicious software. However, it can also interfere with the installation of certain drivers. To turn off UAC, go to the Control Panel and select User Accounts. Then select Change User Account Control settings and set the slider to Never notify and click OK. Restart your computer and try to install the printer driver again.

These are some of the methods you can use to fix the Access denied (code 700) error when trying to install a printer driver. If the issue persists, it is recommended to contact the printer manufacturer for further assistance.
