HowTo / Notes

.NET Framework 2.0 installation

Make sure you operate on a clean 32-bit WINEPREFIX (~/.wine)!

Installation by using 'winetricks' script

Use this option for easy installation of .NET 2.0 Framework. Winetricks will take care of all needed installation prerequisites and work around some problems.


Always use the latest 'winetricks' script from the URL above! Several Linux distributions package outdated 'winetricks' versions, don't use them.

Mono uninstallation

Mono (free alternative .NET Implementation) and Microsoft .NET Framework don't mix well in same WINEPREFIX.

If you intend to manually install .NET Frameworks make sure you removed any previous install of 'MONO' package from WINEPREFIX before.

$ wine uninstaller --remove '{E45D8920-A758-4088-B6C6-31DBB276992E}'


You don't need this step if you use 'winetricks' to install Microsoft .NET Frameworks.

.NET Framework 2.0 Service Packs installation (SP1, SP2)
­­­­Make sure you operate on­ a clean 32-bit ­WINEPREFIX (~/.wine)!

­Installation by using 'winetricks' script

Use this option for easy installation of .NET 2.0 Framework Service Pack(s).

Winetricks will take care of all needed installation prerequisites and work around some problems (.NET 2.0 already installed, Service Packs already applied...).

$ wget


.NET Framework 2.0 Service Pack 1:

$ bash winetricks dotnet20sp1

.NET Framework 2.0 Service Pack 2: ­

$ bash winetricks dotnet20sp2

There is no need to manually install .NET Framework 2.0 be­­fore. Winetricks does this as part of service pack install!­

Verify .NET Framework installation using .NET Framework Setup Verification Tool (Microsoft)

To verify .NET Framework installation(s) in WINEPREFIX you can use the .NET Framework Setup Verification Tool from Aaron Stebner (Microsoft) which checks for proper installation of .NET assemblies and registry entries.

Website and download here­

Select the .NET Framework you want to verify and evaluate the log file manually if verification failed.

Unattended installation of .NET Framework 2.0

­See HOWTO Methods: refer to "manual" installation method what steps are needed before running the installer in unattended mode

Example command lines you can use to perform unattended installations for t­he .NET Framework 2.0 installation­:­

Silent installation

These command lines will run the .NET Framew­ork 2.0 setup in fully silent mode. The setup package will extract to a temporary location and installation will begin with no user interaction and no visible UI. The user will see no visible indication that setup is running.­

$ wine setup.exe /q:a /c:"install.exe /q"

Standard unattended installation

These command lines will run the .NET Framework 2.0 setup in standard unattended mode. The setup package will extract to a temporary location and installation will begin with no user interaction. A progress dialog will appear on the screen during installation, and it will disappear when setup is complete. Errors encountered during installation might pop up message boxes during installation if they occur.

$ wine setup.exe /q:a /c:"install.exe /qb"

Unattended installation with no cancel button available in the UI

These command lines will run the .NET Framework 2.0 setup in unattended mode with no cancel button. The behavior of setup is the same as with the command lines above except the cancel button will be hidden on the progress page during installation. This allows the user to know that a setup is in progress but prevent them from cancelling it (unless they kill the process).

$ wine ­setup.exe /q:a /c:"install.exe /qb!"
Manually trigger rebuild of the Global Assembly Cache (GAC) after .NET Framework installation

Use the following command to manually trigger GAC rebuild after .NET Framework installation (or if WINEPREFIX changed due to Wine update):­

$ wine "c:\\windows\\Microsoft.NET\\Framework\\v2.0.50727\\ngen.exe" update

Some errors (while loading dependent modules that are not GAC'd yet) are expected and can be ignored. ­

fixme:shell:URL_ParseUrl failed to parse ...

URL_ParseUrl FIXME messages on console when running/installin­g .NET apps are harmless and can be safely ignored. Example console output:

fixme:shell:URL_ParseUrl failed to parse L"mscorlib"
dotnet20sp1 install completed, but installed file ... /c:/windows/assembly/NativeImages_v2.0.50727_32/indexb.dat not found­

If you encounter this error while trying to run 'winetricks dotnet20sp1' recipe:

dotnet20sp1 install completed, but installed file /home//.wine/dosdevices/c:/windows/assembly/NativeImages_v2.0.50727_32/indexb.dat not found­

"indexXX.dat" files get changed (number increments) each time a native assembly is generated and installed into GAC (ngen run).

It's an error in older winetricks versions that relied on these numbers.

You can verify this by running full GAC rebuild (optional):

$ wine "c:\\windows\\Microsoft.NET\\Framework\\v2.0.50727\\ngen.exe" update

After this command new index files have been generated.

Please update your winetricks script to a newer version (see main HOWTO)

err:msi:HANDLE_CustomType34 Unable to execute command

If you see an error message at the end of the installer i­n console like this:

­err:msi:HANDLE_CustomType34 Unable to execut­e command L"\"C:\\windows\\Microsoft.NET\\Framework\\netfxsbs20.exe\" /install"

This message is harmless and expected (see my comment here).

/home/yourlogin/.wine is not owned by you / (Permission denied)

Never run wine as root (su, sudo)! Wine doesn't require to be run as root!

You will screw your WINEPREFIX and possibly other things up. If you have run Wine as root you need to:

$ sudo rm -rf ~/.wine­­

and then run winecfg to set Wine folder structure back up. If you used winetricks script as root you might also need to:

$ sudo rm -rf ~/.cache/winetricks/

Again: Just run wine as regular user and all should be fine.

This product is not supported on a 64-bit operating system. Setup will now exit.

This is because you are running the 32-bit installer in a WoW64 Wine. ­There are two ways to overcome this:

Method 1: create 32-bit WINEPREFIX

Set environment variable "export WINEARCH=win32", create a new WINEPREFIX and run the installer

Method 2: "hack" to force install into 64-bit WINEPREFIX

It is possible to install 32-bit .NET Framework in 64-bit prefix (shared Wow64 enviroment):

In order to do this: run the .NET installer as follows:

$ wine dotnetfx /C

It will ask you for a folder to put extracted files in. After extraction, go to the folder and open up the "install.ini" in text editor.

Change the value under [setup] section:




Now you are ready to run the installer using:

$ wine install.exe

This is only for experts and not the recommended way. Use at own risk! ­

err:eventlog:ReportEventW .NET Runtime version 2.0.50727.42 - Fatal Execution Engine Error (7A05E2B3) (80131506)

If a .NET application exits with the following mes­sage in console:

fixme:advapi:ReportEventW (0xcafe4242,0x0001,0x0000,0x000003ff,(nil),0x0001,0x00000000,0x33b6e8,(nil)): stub
err:eventlog:ReportEventW L".NET Runtime version 2.0.50727.42 - Fatal Execution Engine Error (7A05E2B3) (80131506)"
fixme:advapi:DeregisterEventSource (0xcafe4242) stub

This 'Fatal Execution Engine Error' (80131506) is pretty general and can be caused by many things, for example by bug 10506.­

Please read appdb entry HOWTO more carefully! This is bug 10467.

If you followed appdb HOWTO and this problem still occurs you most likely have a corrupted "l_intl.nls" file in your winetricks cache. Update your winetricks script to newer version (contains checksum for detection of corrupted download) or remove "l_intl.nls" from "dotnet20" folder in "winetrickscache" and repeat the winetricks step.

ngen.exe hangs while compiling a particular assembly (out of file descriptors)

­Reported in Bug 16258. It seems the PE image generator runs out of file descriptors while writing out native images. T­his is a bug in the Microsoft .NET 2.0 Framework. Use the following workaround if you encounter this bug:­

$ su­
# ulimit -n 4096
­# su your_username
­$ wine your_installer­­
