win32 --mixed-mode can't load mscorlib.dll, but it is present

[HinTak]

revisiting #10268 , now the error sufficiently different so I am opening a new bug:

The assembly mscorlib.dll was not found or could not be loaded.
It should have been installed in the `C:\Program Files\Mono\lib\mono\4.5\mscorlib.dll' directory.

H:\>"C:Program Files/Mono/bin/mono.exe" --version

This is just the official build https://download.mono-project.com/archive/6.12.0/windows-installer/mono-6.12.0.107-gtksharp-2.12.45-win32-0.msi
, running under wine staging 6.2 .

"C:\Program Files\Mono\lib\mono\4.5\mscorlib.dll" is definitely present there (I didn't do anything different from just pressing next with the installer). Maybe wine's mscoree.dll (which mscorlib.dll depends on) is not good enough? Or maybe support for mixed-mode assembly is still buggy?

Steps to Reproduce

1. install https://download.mono-project.com/archive/6.12.0/windows-installer/mono-6.12.0.107-gtksharp-2.12.45-win32-0.msi under wine
2. download the fontval hybrid build from the url referenced

"C:Program Files/Mono/bin/mono.exe" --mixed-mode  z:/tmp/RELEASE_2016_02_08.hybrid/bin/FontValidator.exe -file z:/usr/share/fonts/wine-times-new-roman-fonts/times.ttf +raster-tests -report-dir z:/tmp/b

or any font, really.

Current Behavior

The assembly mscorlib.dll was not found or could not be loaded.
It should have been installed in the `C:\Program Files\Mono\lib\mono\4.5\mscorlib.dll' directory.

Expected Behavior

should run complete.

Stacktrace

The assembly mscorlib.dll was not found or could not be loaded.
It should have been installed in the `C:\Program Files\Mono\lib\mono\4.5\mscorlib.dll' directory.

without --mixed-mode it crashes wine, which is not surprising:

It seems to have gone worse since I last tested it - it used to get a bit further and output runtime version then reflects on the input font name, according to what I wrote in #10268 :

WARNING: The runtime version supported by this application is unavailable.
Using default runtime: v4.0.30319
c:/Windows/Fonts/times.ttf (file 1 of 1)
... a lot of info...

these are still outputted without --mixed-mode.
