Hello! Tonight, our computers have updated Intell Graphic Driver. After that, our application (Developed in our company began to fall on the initialization of OpenGl (wglCreateContext -> Access Violation in ig9idc32.dll)).

[KErmo]

Computers:

Windows 10 Pro x64

CPU: i5-7400

Version of the graphics driver: 25.20.100.6323 from 11/18/2018

When the driver rolls back (up to version 23.20.16.4978 from 02/28/2018), the performance is restored.

How can this be corrected?

I also checked OpenGl with glewinfo.exe:

Hi KErmo, Thank you for posting in the Intel® Communities Support. We recommend to install the graphics driver provided by the manufacturer of the computer, since that driver was customized by them work with your specific platform. What is the model of the computer? The driver version 25.20.100.6323, is that driver provided by Dell? In order to correct the issue, since the processor works with Intel® HD Graphics 630 we can also try to install the Intel® generic graphics driver version DCH 25.20.100.6519: https://downloadcenter.intel.com/download/28515/Intel-Graphics-Driver-for-Windows-10?product=98909 Regards, Alberto R.

Hello!

The computer is assembled from the components on its own.

All drivers are downloaded via Windows Update.

The drivers you provided could not be installed.

The installer says: "This installation package is not supported by this type of processor."

Hello KErmo, Thank you for letting s know that information. In order for us to look for the proper graphics driver please provide the model of the computer? As an option, we can also try to install the graphics driver manually: https://www.intel.com/content/www/us/en/support/articles/000005629/graphics-drivers.html Regards, Alberto R.

KErmo, We are sorry to hear the issue persists, please provide the model of the computer so we can further assist you. In the mean time, we can try the following steps to install, first the driver provided by Dell, then if the problem persists then we can try to install the Intel® generic graphics driver version DCH 25.20.100.6519: 1. Download the latest DCH driver. 2. Daisconnect your unit from the Internet to prevent Windows* Updates from installing any other driver. 3. Uninstall the DCH driver and the Intel® Graphics Control Panel from Control Panel > Programs and Features. 4. Restart the computer. 5. Make sure the 'Microsoft Basic Display Adapter' is listed under Windows* Device Manager > Video adapters. If not, repeat steps 2 to 4. 6. If the adapter continues to be listed as ‘Intel HD Graphics’, and no other Intel® Graphics driver is listed under 'Programs and Features' for removal, then it means Windows* has switched to a previously installed Legacy driver. At this point, we can remove Legacy drivers from Device Manager: 6.1.1 Right-click on 'Intel HD Graphics' or similar, and select 'Uninstall Device' 6.1.2 In the pop-up window make sure 'Delete the driver software for this device' is checked. 6.1.3 Click on 'Uninstall'. 6.1.4 Restart. (Repeat steps 6.1.1 through 6.1.4 until the device gets listed as 'Microsoft Basic Display Adapter') 7. Install the DCH driver that was downloaded on step 1. 8. Restart the computer. 9. Enable your Internet connection. 10. Download the Intel Graphics Control Panel from the MS Store. As an option you can always use the Intel® Driver and Support Assistant to update the drivers: https://downloadcenter.intel.com/download/28425/Intel-Driver-Support-Assistant?product=128824 Regards, Alberto R.
