mf-install is ok, but I can't do the mf-installcab about mf-installcab

A more detailed explanation:
After I installed mf-install.sh, I tried this:

command 1:
PROTON="/home/xadai/.steam/steam/steamapps/common/Proton 4.11/" \ WINEPREFIX="/home/xadai/.steam/steam/steamapps/compatdata/397540/pfx" ./install-mf-64.sh -proton

output 1:
bash: WINEPREFIX=/home/xadai/.steam/steam/steamapps/compatdata/397540/pfx: No such file or directory

command 2:
PATH=/home/xadai/.steam/steam/steamapps/common/Proton\ 5.0/dist/bin/:$PATH WINEPREFIX="/home/xadai/.steam/steam/steamapps/compatdata/397540/pfx" ./install-mf-64.sh

output 2:
mediafoundation

File "installcab.py", line 318, in
output_files = extract_from_installer(cabfile, tmpdir, component)
File "installcab.py", line 207, in extract_from_installer

I have a similar problem but with different error output.

Make sure cabextract is in your path

I've faced the same problem and it turns out that the file on the Internet Archive is either broken somehow or the transfer gets interrupted and only part of the file is downloaded. After looking at https://web.archive.org/web/20200803210804/https://download.microsoft.com/download/0/A/F/0AFB5316-3062-494A-AB78-7FB0D4461357/, I've found this alternative url on microsoft site to be working and providing the full file: http://ak.or.download.microsoft.com/download/0/A/F/0AFB5316-3062-494A-AB78-7FB0D4461357/windows6.1-KB976932-X64.exe
For completeness, here is sha256 sum of the working file:
f4d1d418d91b1619688a482680ee032ffd2b65e420c6d2eaecf8aa3762aa64c8 windows6.1-KB976932-X64.exe

I am getting this error when trying to install it: ./install-mf-64.sh: Line 32: wget: Command not found.
The other MF install worked though (mf-install).

Install wget with your distro's package manager.
