Reducer throws an Unhandled exception upon clicking to browse for ISO, running on a Reduced win 10 x64, so I wonder what have I removed for this to happen. Seems like the application can't find the system's browser ?

Code:

Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue.
If you click Quit, the application will close immediately.

Creating an instance of the COM component with CLSID {DC1C5A9C-E88A-4DDE-A5A1-60F82A20AEF7} from the IClassFactory failed due to the following error:
80040111 ClassFactory cannot supply requested class (Exception from HRESULT: 0x80040111 (CLASS_E_CLASSNOTAVAILABLE)).



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.

Still throws exceptions on untouched windows installation [17763.316 Enterprise LTSC]
Is .NET so touchy or what

It seems that if Visual Themes feature is turned off for whatever reason, Windows would hide the COM interface and lead to the crash. However, this answer does not provide any specific workaround.

After pulling a lot of hairs out, I finally found it. Using High Contrast theme crashes .Net on file dialog. Beautiful.
