I am sorry for this issue you have encountered.
The driver version you mentioned above is the latest for Intel® HD Graphics 4000; however, you can try using the driver linked below if the system includes Intel® HD Graphics 4200 or higher.
Is this application publicly available for download?
Kindly attach the Intel® HD Graphics report and DxDiag report (press Windows* key + R key, type “dxdiag”, press OK and then click “Save All Information”). You may attach the files by using the Advanced Editor option from the upper right corner of the text box when replying.
When I attempt to open the Intel Graphics Control Panel, the splash screen opens for a few moments, but then it disappears and nothing happens.
I do not have access to other Intel hardware, and it would be quite difficult to test, since it may require a different motherboard.
Our application demo is available for free on Steam:
Would it be possible for you to try uninstalling and reinstalling the driver (188.8.131.52.3621) to see if the Intel® HD Graphics Control Panel UI opens?
I read from the Leadwerks* forum that one user has Intel® HD Graphics 4600, so perhaps this person can try with the driver version I linked above (184.108.40.206.3907).
We have isolated the issue and are currently implementing fix for upcoming drivers. I will post an update to this thread when the driver is available for download at Intel Download Center.
Has there been any progress with this? I notice there was a driver update in October but it does not appear to resolve the issue. The holiday sales season is upon us and it's not going to be good if 20% of new customers can't run the program they just bought.
