Additional Comments

Use 'winetricks' script for installation of .NET Framework 1.1 - especially if the app wants to install it on its own! Always use a clean WINEPREFIX for .NET installs (Framework + .NET based app)!

HowTo / Notes

Get winetricks!

Install winetricks (more details here) to make easier to configure the Wine prefix:

$ sudo wget '' -O /usr/local/bin/winetricks
$ sudo chmod +x /usr/local/bin/winetricks
.NET Framework 1.1 installation

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

Method 1: Installation by using 'winetricks' script

Use ­this option for easy installation of .NET 1.1 Framework.

­Winetricks will take care of all needed installation prerequisites and wor­k around some problems.

Method 2: Manual installation

Run the installer of .NET Framework 1.1

Optionally install corefonts (using winetricks)

Post-installation issue: ­

If you intend to use .NET 1.1 Framework without upgrading to .NET 2.0 or later you might need to set a load-order override of "mscoree.dll" library (system32) to "builtin" only (using winecfg).

This is due to different loader implementation between .NET 1.1 and 2.x (or later), see bug 17184­ for explanation.­

.NET Framework 1.1 Service Pack 1 installation
­­­­Installation by using 'winetricks' script

Use this option for easy installation of .NET 1.1 Framework Service Pack(s).­

Winetricks will take care of all needed installation prerequisites and work around some problems (.NET 1.1 already installed, Service Packs already applied...).

$ wget

.NET Framework 1.1 Service Pack 1:

$ bash winetricks dotnet11sp1

There is no need to manually install .NET Framework 1.1 be­­fore. Winetricks does this as part of service pack install!­­

Unattended installation of .NET Framework 1.1

Unattended Installation

Example command lines you can use to perform unattended installations for the ­.NET Framework 1.1 installation­: ­

Silent installation

These command lines will run the .NET Framework 1.1­ 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 1.1 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 1.1 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!"
Verify .NET Framework installation using .NET Framework Setup Verification Tool (Microsoft)

Last update: 2023-06-16

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

$ wget ''
$ unzip
$ env WINEPREFIX=$HOME/winedotnet wine ~/netfx_setupverifier.exe

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

RegAsm.exe - Fatal error: CLR error: 80004001. The program will now terminate

This is bug 25120. You need to set "fusion" component to "native".

Either use 'winecfg' tool or start the installer as follows (if you don't use winetricks recipe):

$ WINEDLLOVERRIDES=fusion=n wine ./dotnetfx.exe

Failed to delay load library mscorlib.dll (Win32 error: 0)

If you get a message box telling:

Failed to delay load library mscorlib.dll (Win32 error: 0).
This program can no longer run and will now terminate.


This is bug 25120

Use winetricks for installation.

fixme:shell:URL_ParseUrl failed to parse ...

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

fixme:shell:URL_ParseUrl failed to parse L"mscorlib"

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\\netfxsbs11.exe\" /install"

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