looks like it gets confused because of the expected compression... It can open an install.esd but not an install.swm that was created by splitting the install.esd.
Click to expand...

what happens if you rename install.swm to install.esd, rename install2.swm to install2.esd etc.

Let's convert MCT's SWM back to a normal WIM...
Code: 
DISM /export-image /sourceimagefile:D:\sources\install.swm /swmfile:D:\sources\install*.swm /sourceindex:1 /destinationimagefile:install.wim

1. wimlib can't read the WIM
2. 7z.exe can extract wlanapi.dll

You don't mind creating a 5.28 GB temp file (install.wim) just for this?!

To cap our headache:
  • When MCT saves to a local ISO file, files from the ESD image can be extracted without the expense of mounting the ESD image. But we cannot re-use the same ISO file (within MCT) to create an USB drive. You must use Rufus or other means.

  • When MCT saves to a local USB, files from the SWM image cannot be extracted. You can't mount a set of SWM files, so they must be converted back to WIM or ESD first. This requires having quite a bit of free disk space.

  • If you use DISM to convert the original ESD file (from save to ISO) as SWM, this works. But MCT's conversion process changes the format to break 3rd-party tools. Why would MS decide to have MCT perform the conversion differently from DISM??

Yeah...

I was able to get the two DLLs in AppData\Local\Temp this way, without mounting anything...

cd C:\Program Files\7-Zip

Dism /Export-Image /SourceImageFile:E:\sources\install.swm /SWMFile:E:\sources\install*.swm /SourceIndex:1 /DestinationImageFile:C:\Users\Jim\AppData\Local\Temp\NewInstall.wim

Then -

7z x "C:\Users\Jim\AppData\Local\Temp\NewInstall.wim" "Windows\System32\wlanapi.dll" "Windows\System32\mobilenetworking.dll" -o"C:\Users\Jim\AppData\Local\Temp"

Note: This extraction approach created Windows\System32 folders in AppData\Local\Temp

Extracted DLLs.webp

I'm sure you'll come up with a cleaner way.

add $TEMP_DIR\Windows\System32\wlanapi.dll /Windows/System32/wlanapi.dll
add $TEMP_DIR\Windows\System32\mobilenetworking.dll /Windows/System32/mobilenetworking.dll

Remove-Item "$TEMP_DIR\\Windows\System32\wlanapi.dll","$TEMP_DIR\\Windows\System32\mobilenetworking.dll"

Booted from the MCT USB, and accessed the Repair function with no issues.
