Error code 5: Access is denied - AsIO3.sys!!

I've read all the threads about this error. Looked at video's on youtube and none have resolved this error. I have come to the awful conclusion that this error is generated due to some strange marriage of Asus software that has dependencies on each other.

My rig is a TUF z490 with Wifi, Asus RTX 3090 24 OC and Asus ROG Strix XG27UQ 27" 4K UHD 3840x2160 144Hz HDR DSC Gaming Monitor.

My Asus software installed is ASUS Framework Service, ASUS Motherboard, AURA, Aura Creator, Aura lighting effect add-on (+x64 version) and Aura Service.

All of the above software are the latest versions.


I don't have AISuite or Armoury Crate installed.

The error code 5: Access is denied - AsIO3.sys randomly pops up every hour or so.

Any suggestions to eradicate this error permanently would be appreciated.

Thanks

Malware scan with Malwarebytyes and open CMD admin and ender....... sfc /scannow

I got the same error message during motherboard HAL installation of armoury crate and aura creator setup. Indeed, opening armoury crate i cannot access to the strix z370-f page and configure the connected led strips.
I tried to unistall every asus sw with revo and then i run dism and sfc, but that AslO3.sys is still present in C:\Windows\drivers directory.
So i tried to remove it using windows 10 safe mode and reinstall armoury crate. The message does not show up anymore but armoury doesn't recognize any device.
I'm just wondering how to repair that driver. Does anyone know if there is some setup package that install that driver?
It would be awesome if someone can help me with this without reinstalling windows. Thanks in advance

It should be caused by a registry residue after uninstalling Armoury Crate before, which caused this control to not be installed normally, and it was necessary to clean up a certain registry and driver files of ASUS to solve it.

1) press WIN+R
2) input: REGEDIT
3) path to: Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\
4) find: "Asusgio2" and "Asusgio3" folder in the left tree window.
5) check the right window, remember the [ImagePath], just like mine is "C:\Windows\system32\drivers\AsIO3.sys"
6) delete these two folders "Asusgio2" and "Asusgio3" in the left tree window in regedit.
7) delete these two files "AsIO2.sys" and "AsIO3.sys" in the path "C:\Windows\system32\drivers"
6) reboot your computer, done!!

Just use Armoury Crate uninstaller from asus site... its so simple...

That works and I can use it, to uninstall it, BUT, I keep getting the AsIO3.sys can't open error code 5 every time I try to re-install even after using the Armoury Crate Uninstall Tool, and turingn off my Anti-Virus program. to try re-installing Armoury Crate(Latest Version 5.3.2.1)

Unfortunately, I keep getting this error, even when I have neither of the two pesky AsIO2.sys or AsIO3.sys

FILES BOTH are located in C:\Windows\System\Drivers after a FAILED Armoury Crate install. They are BOTH gone after I use the Armoury Crate Uninstall Tool. I'm pissed. I did have it installed once.
