Microsoft doesn't provide an out-of-the-box driver in Windows 11 ARM for the VMware vmxnet3 virtual network adapter like they do for Windows x64. When using ISO installation media that was not created by Fusion (that is from CrystalFetch or UUPdump), a network will not be found due to the lack of this driver.
While Windows 11 ARM 24H2 now will prompt you to install a driver when a network device isn't found (this wasn't the case in 23H2 and earlier), wouldn't it be nice if there was a way to include the vmxnet3 driver in these Windows 11 ARM ISOs so it would be installed for you automatically? And wouldn't it be nice if you didn't have to use a Windows system to do it?
Well, now there is. I wrote a script to re-build these ISOs to include the vmxnet3 driver.
You can find the script on GitHub (see the below link).
Version 1.0.0b2 has just been released. It fixes a couple of bugs and has been tested with the newly-released Windows 11 ARM ISO that's available from Microsoft. If you find a bug in the script, please open an issue on GitHub -- I will not respond to bug reports posted in this thread.
