I am unable to update my graphics card driver.

[Catgray]

As shown in the picture, every time I try to update the driver, I encounter this error. I purchased a B580 in May, and since then, I have been updating the drivers without any issues until recently. At first, I didn’t pay much attention and planned to update later. However, when I realized I had missed several driver versions, I tried to resolve the issue but couldn’t find a solution. Please help me. Thank you.

Additionally, the Chinese text in the image reads: '无法调用方法。此语言模式仅支持核心类型的方法调用。所在位置 行:4 字符：1'. I hope this information is helpful for you.

Hello Kent,

Regarding your first four questions:
The PowerShell version I am using is 5.1.26100.6899. I did not launch PowerShell manually—I simply ran the update program downloaded from the official website as usual, and then the PowerShell error appeared. I did try running the update program with administrator privileges, but it didn’t help.

For your fifth and sixth questions:
My Windows updates automatically. Since the issue did not appear recently, I can’t confirm whether it was caused by a specific update. I have never modified PowerShell execution policies or installed any security software.
Considering that my current driver version is 32.0.101.8132, and the next version (32.0.101.8135) was released on October 1st, the issue must have started occurring after October.

I have attached the files you requested. Looking forward to your reply.

Hi Catgray,

Thank you for your patience. To assist with the investigation and further review of your concern, could you please answer the following questions:

• Have you tried rolling back the Windows update?
• Have you used Display Driver Uninstaller (DDU) before installing or updating the graphics driver?

Best regards,

Hello, thank you for your reply. I tried rolling back the recent two quality updates for Windows, but it didn't resolve the issue. Regarding DDU, I didn't use it before updating—I just ran the update program directly. Although I did consider using it to uninstall the driver and then reinstall it after the driver installation failed, given the current situation, I was concerned that I might not be able to reinstall the driver after uninstalling it, so I didn't dare to proceed. Looking forward to your reply. Thank you.

Hi @Catgray,

I am reaching out on behalf of my colleague. Based on my assessment, this appears to be an installation issue. Kindly try performing a clean installation of the graphics driver using DDU (Display Driver Uninstaller), then install the latest graphics driver version 32.0.101.8250.

Once completed, please let me know if the issue remains unresolved.

Best regards,
