Windows 11 24H2 as host - Configuration 12.0 VMs aren't using NVidia drivers (Error 43)

[dante102]

Description

Virtual machines created using Hyper-V on a "Windows 11 24H2" host cannot utilize the gpu after executing the GPU-PV script.
Inside the VM, The "dxdiag" command does not show the "Render" tab, and the "Display" tab shows an error message:

Steps to reproduce

Method 1: New VM on 24H2 Host

1. Host OS: "Windows 11 24H2".
2. Create a Gen2 VM with "Windows 11 24H2" as the guest OS.
3. Run the "Easy-GPU-PV" script (see solution Update-VMGpuPartitionDriver can't find driver letter #404 if driver file copying fails).
4. Launch the VM, enter Run (Win+R)" and execute "dxdiag".

Method 2: Existing VM Conversion (the long way)

1. Host OS: "Windows 11 22H2".
2. Create a Gen2 VM with Windows 11 22H2.
3. Run the "Easy-GPU-PV" script (see solution Update-VMGpuPartitionDriver can't find driver letter #404 if driver file copying fails).
   3.1. Optional: Launch the VM, open Run (Win+R), and execute "dxdiag" to verify functionality - should show the "Render" tab and no errors in "Display" tab.
4. Close the VM and update the Host to 24H2.
   4.1. Optional: Launch the VM, re-run "dxdiag" to confirm functionality - should show the "Render" tab and no errors in "Display" tab.
5. Recreate a VM using the virtual hard disk of the existing Gen2 VM.
6. Launch the new VM, open Run (Win+R)", and re-run "dxdiag".

Expected Behavior

Inside the VM, the "Render" tab should appear in dxdiag, indicating that the GPU is functional.

Actual Behavior

The "Render" tab is missing, and the GPU is not functional.

Cannot replicate. Works fine on my end. Are you using the latest Nvidia driver? I am on 565.90.

[dante102]

Correct, i am using the latest display driver (version 565.90).

I will be closing this thread. The issue was found and it was me not being able to follow basic instructions - i have been launching the wrong script (Interactive-Easy-GPU-PV instead of Easy-GPU-PV).

The Easy-GPU-PV had no issues finding the drive letter and the "Render" tab is visible in "dxdiag".
