Unable to install driver for AC8265

[OcRzr]

I have a Win10_64 machine that I was prepping for Win11.  Somewhere in that process the Intel Driver & Support Assistant tried to update the driver for my AC8265.  It fails saying "one or more issues caused setup to fail".  Error log attached.  ChatGPT has run me in circles for hours, I have no idea which way is up at this point.  Any help very much appreciated

The 8265 module and cards have been discontinued by Intel. Still, there appears to be a lot of availability on Amazon (though much of it is Chinese companies putting the module on their own, questionable quality, knockoff cards - and then using the Intel label to make it look like it all came from Intel; slimy, really slimy). I rant.

Ok, down to it. The last package version providing drivers for the 8265 is v22.200.2. What Intel doesn't tell you is that attempting to install later package versions can have negative results beyond just a failing installer (which iDSA presents over and over and...). You could end up with a very old driver being installed without knowing it. Bottom line, you want to either ignore or hide any subsequent packages that are proposed for installation. In iDSA, support is provided for either temporarily or permanently hiding any of these packages that appear. In Windows Update, you can use the Windows Update Show-Hide tool (attached) to hide these packages.

You can download the v22.200.2 driver package here: Intel® Wireless Bluetooth® Drivers for Intel® Dual Band Wireless-AC 8260 and Intel® Dual Band Wireless-AC 8265.

Hope this helps,

Very much appreciate the help.  The wireless adapter had stopped functioning - couldn't get any driver to load for it.  After posting above I went ahead and just upgraded to Windows11.  Lo and behold the AC8265 was loaded up and working immediately after install - didn't do a thing.  *shrug*

What's the version of the driver that is running? 20.70.32.1?

Update:  after upgrading to Win11 I started getting the warning below saying that driver iqvw64e.sys can not load.  Looks like this is maybe related to the Intel Network Adapter Diagnostic Driver and the enabling of Memory Integrity?  Wondering if this was the issue all along?  Anything I should do here?  The AC8265 wireless adapter is currently working.

This happens during Windows 11 upgrades when a very old and incompatible driver is still on the system, left behind in a prior - in this case Intel - driver update. In some cases, these drivers block the Windows upgrade, in others this is the result.

You can do the following:

1. Open the Windows Security app.
2. Select Device Security.
3. Click on Core Isolation Details.
4. Attempt to Enable Memory Integrity.
5. If this fails, a list of the problematic driver(s) will be made available. If you click on each driver, most will display the name of an OEM .INF file (OEM890.INF, for example).
6. If you can sort out which installed package installed these old drivers, you can simply uninstall them. In other cases, you have to invoke the nuclear option. That is, for each of the OEM .INF files identified, execute command:

"pnputil /delete-driver <oem#.inf> /force /uninstall"

Hope this helps,

P.S. In these dialog boxes, never select the Don't show this message again option.
