Hi punktoe.
Are you performing this in a VM, or on a physical machine running windows 8.1?
Can you try to extract the iso manually to a folder using PowerISO or even with 7zip/winrar. Then load the folder in WinReducer?

This is what I do. I create a copy of the extracted ISO folder and just copy over the contents to the folder that I previously reduced when I want to perform another reduction. I never have any issues using that process.

I think I'm having the exact same problem and fixed it. The problem does NOT lie in extracting the files from the ISO file: this is done perfectly fine in the background and matches manual extraction. The problem must occur on attempting to mount the WIM file: after extraction I do get the dialog to choose between the WIM's editions (Pro or Core).

This is on a Windows 8.1 x64 machine, no VM.

The full exception error:

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.


Solution
I could fix it by finding the folder within %WinDir%\WinSXS containing the files:
wimgapi.dll
wimserv.exe

and copying those files into %WinDir%\System32

Second, I copied wimmount.sys (from the same folder in %WinDir%\WinSXS) into %WinDir%\System32\Drivers
