Intel UHD Graphics 620 won't install - fatal install error

[AngieM357]

I use Adobe Premiere Pro daily. Until yesterday, when I got an error that my graphics driver was suddenly unsupported. I read their instructions and chose to go through Intel first.

- Intel's downloads didn't work because the drivers on this laptop are customized through HP.

- HPs downloads didn't work because who knows why? The support assistant utility runs forever before finally giving an error. If I find the appropriate driver from a list, it gives me a fatal error message.

- But then, when I looked in the device manager, the events list said that it requires further installation. Well, duh. But what do I do about it? Dunno.

- I tried using the IFGX zip file Adobe suggested. It gave me the same "customized driver" error message that I got from the Intel site. 

- I've tried every suggestion and "fix" the HP automated virtual assistant has put out there and the driver is listed as working correctly with no errors, there are no updates through device manager, Windows just updated again this morning and I tried all of these methods again in case THAT was the issue, but to no avail. In fact, the HP assistant utility NOW has been "installing" this one driver for about an hour and a half...

I'm afraid if I wipe this thing and start over, I'm going to still have the same issue when I get it all up and running again. I'd like to try to solve this without all that mess, if possible.

Hi:

Does your notebook have the onboard Intel graphics only, or does it have a switchable graphics combination?

If it only has the onboard Intel graphics, see my knowledgebase article at the link below for how to manually update the Intel HD graphics driver to the latest version found on the Intel website.

It seems to have worked except that now everything is laggy. Not ideal when you're trying to edit video! But I guess I needed to try to install it through the device manager instead of the other methods because that's what finally got it to fully install and make the error disappear. Any clue about how to rectify the sluggish response?

Thank you so much for your help; I couldn't figure out why I'd done All The Things and none had worked!

You're very welcome.

Unfortunately, I wouldn't be able to help you with that issue.

Are you sure that your notebook only has the onboard Intel graphics?

When you use the method I wrote about and your PC has switchable graphics, it prevents the switchable graphics from working.

See the second comment below my write-up.

If you are sure your PC only has the onboard Intel graphics, everything should be working normally.
