"Open driver handle failure" crash on Z370 Aorus Gaming 5 about rgb-fusion-tool HOT 8 OPEN

I fiddled with this and finally got somewhere: it looks like if you never run it as an Administrator it can't install gdrv.sys and you'll get this error. It seems that ycc.dll installs gdrv.sys if it's not present.

I have this almost identical error using a Z390 Pro WiFi motherboard.

I was running the commands in an elevated powershell terminal. I'm not sure I follow what I could do to correct the issue.

Darn, in that case I think you're doing all you can. You could try a support ticket with Gigabyte per the other thread in the meantime.

So after a few more restarts, I no longer get any errors but it doesn't seem to do anything. When running commands it outputs nothing. Only help results in any output.

Guess it is back to the SDK not supporting the new boards.

Edit: I also contacted support but don't expect much.

I’m running into this. Where/what is that gdrv.sys you mentioned above?

Also have you noticed GLedApi doesn’t work at all when under 64bit process? I’m also testing a bit.

Btw, i just noticed that RGBfusion install has a Gigabyte.NativeFunctions.dll which does some extern pinvokes into ycc.dll as well.

@ericnewton76 gdrv.sys would live in C:\Windows\gdrv.sys; though if it's not maybe don't rush get it going until they've patched issues like CVE-2018-19320.

I'd say native 64-bit support would be a separate issue (I'm not sure how far I could get since Gigabyte's DLLs are 32-bit, though).

They seem to be all over the place in the RGB Fusion packages they ship; I'm really hoping I can get them to star publishing interface docs so we can wrap it with a unified API.

just got a z390 mobo im running corsairs watercooler that comes with icue and does take over the rgb lighting. i have no idea 3d osd even is because it will not start due to the corsair h150 water cooler software. rgb fusion works fine though. not sure whats going on but i have the same errors. its 2023 though.
