Nexus Mod Manager Forum

The latest installer seems to run fine, but although the bottle has .Net 3.5 installed already, it downloads and installs .net 3.5, but then it doesn't work when it's launched.

Here's how it fails:

Here's the recommended fixes (aka wine tricks) from wineHQ, not sure how many of these are possible with Crossover:

Create clear wineprefix. Update winetricks. Disable window managment & decoration in winecfg because lags with focus on form when show hints.

# GDI+ for .NET Framework (optionaly)
winetricks -q gdiplus_winxp
# MS XML 3 for .NET Framework 3.5
winetricks -q msxml3
# Internet Explorer required for work NMM
winetricks -q ie8
# Remove winemono
wine uninstaller --remove '{E45D8920-A758-4088-B6C6-31DBB276992E}'
# DLL override for correct setup .NET Framework
export WINEDLLOVERRIDES=ngen.exe,mscorsvw.exe=b
# .NET Framework 2.0 SP2 (http://www.microsoft.com/en-us/download/details.aspx?id=1639)
wine NetFx20SP2_x86.exe /lang:ENU /q
# .NET Framework 3.5 SP1 (http://www.microsoft.com/en-us/download/details.aspx?id=25150)
wine dotnetfx35.exe /lang:ENU /q

Edit by maintainer:
As stated by the OP, several game modes require replacing their respective DLLs with versions recompiled under Mono.
Fallout3, FalloutNV, Morrorwind, Oblivion and Skyrim DLLs can be downloaded here: http://goo.gl/tZF4z6
The respective source code can be found here:

I'll try to check some things when I get time - one suspicion I have is that it's the .net xml library and maybe the overrides.

Heya,

As per winehq instructions here's what I got into a clean bottle:

Core Fonts
MSXML3
.NET 3.5 SP1 (yes this matters)
IE 8 which also dragged in Flash Player (oh well)

then installed the latest version on NMM.

It started but then threw and error and it would close.

Well, what the... let's see NMM logs shall we?

I did, I did taw a puttytat! Turns out that one of the dirs NMM was searching through did have a colon in the name, which according to windows file/folder naming conventions is a no-no and so the thing choked in a less than graceful way. UNIX (Mac OS X is unix) and Linux do not impose the same restrictions and described below:

You can add "virtual drives" to the bottle where NMM is installed, like the folder where Skyrim is installed. Check the Wine Configuration utility in the Control Panel tab of the NMM bottle.
