.NET Framework

What works

The installer starts but comes up with the error message:

Your installation will not occur. See below for reasons why.

Details

Same or higher version of .NET Framework 4 has already been installed on this computer.

This happens even with a clean Wineprefix. I tried deleting ~/.wine and running the installer manually and with "winetricks dotnet40" yet it still has this error message.

What does not

Installing does not work.

Workarounds

I tried using "winetricks dotnet40", it had the same error and did not work.

I tried changing the Windows version in the Wine prefix to Windows XP and Windows 2003 as suggested by others, it did not work.

I tried using `--force` on the installer as someone else suggested, it did not work.

What was not tested

I tested everything I could think of.

Additional Comments

Ubuntu 18.04 LTS 64-bit Linux, Wine 4.9 installed from WineHQ repos via the "winehq-devel" package with 64-bit prefix.

File is "dotNetFx40_Full_setup.exe" with MD5 hash 53406e9988306cbd4537677c5336aba4 and I also tried Winetricks

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

$ sudo wget 'https://raw.githubusercontent.com/Winetricks/winetricks/master/src/winetricks' -O /usr/local/bin/winetricks
$ sudo chmod +x /usr/local/bin/winetricks

Create a new Wine prefix (for most applications, it's better to set its own prefix):

$ env WINEPREFIX=$HOME/winedotnet wineboot --init

If Wine prompts for installing Mono, click Cancel.

Install .NET Framework (and optionally install corefonts):

$ env WINEPREFIX=$HOME/winedotnet winetricks --force dotnet40 corefonts

Use dotnet40 to install .NET Framework 4.0. To install another version of 4.x series, change it to one of the following list:

dotnet45   to install .NET Framework 4.5
dotnet451  to install .NET Framework 4.5.1
dotnet452  to install .NET Framework 4.5.2
dotnet46   to install .NET Framework 4.6
dotnet461  to install .NET Framework 4.6.1
dotnet462  to install .NET Framework 4.6.2
dotnet47   to install .NET Framework 4.7
dotnet471  to install .NET Framework 4.7.1
dotnet472  to install .NET Framework 4.7.2
dotnet48   to install .NET Framework 4.8

... And so on. For example, to install .NET Framework 4.5.2:

$ env WINEPREFIX=$HOME/winedotnet winetricks --force dotnet452 corefonts

If this doesn't work or you need to install a version not supported by winetricks, try a manual installation (explained below).

Start with a new Wine prefix:

$ env WINEPREFIX=$HOME/winedotnet wineboot --init

Try to install .NET 4.0 through winetricks:

$ env WINEPREFIX=$HOME/winedotnet winetricks --force dotnet40 corefonts

If it success and you need to install a higher 4.x version, go to Manual Installation (Step 2). If it doesn't work (very unlikely) keep reading.

Uninstall wine-mono from your Wine prefix:

$ env WINEPREFIX=$HOME/winedotnet wine uninstaller --remove '{E45D8920-A758-4088-B6C6-31DBB276992E}'

Change reported version to Windows XP, then download and install .NET 4.0:

$ env WINEPREFIX=$HOME/winedotnet winetricks winxp
$ wget 'http://download.microsoft.com/download/9/5/A/95A9616B-7A37-4AF6-BC36-D6EA96C8DAAE/dotNetFx40_Full_x86_x64.exe'
$ env WINEPREFIX=$HOME/winedotnet wine ~/dotNetFx40_Full_x86_x64.exe

Open winecfg dialog:

$ env WINEPREFIX=$HOME/winedotnet winecfg

Go to "Libraries" tab, add a new library substitution called "mscoree" and set it to "Native (Windows)". Close the dialog by clicking OK.

Change reported version to Windows 7:

$ env WINEPREFIX=$HOME/winedotnet winetricks win7

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

$ env WINEPREFIX=$HOME/winedotnet wine "c:\\windows\\Microsoft.NET\\Framework\\v4.0.30319\\ngen.exe" update

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

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 'https://msdnshared.blob.core.windows.net/media/2018/05/netfx_setupverifier_new.zip'
$ unzip netfx_setupverifier_new.zip
$ 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.

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

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

Some of Wine's truetype fonts are still not in shape of being a complete replacement for Windows ones, causing errors.

You must use 'winetricks corefonts' recipe to work around this problem!

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

You are missing the samba/winbind component which is essential for certain Wine functionality.

Please install winbind with your distribution package manager!

If you encounter this error, the .NET4 app basically requests .NET 4.0 Full Framework. The default for .NET 4.0 Framework is "Client Profile".

Workaround: If your .NET4 application is called "foo.exe", rename "foo.exe.config" to something different and run again.

If this file is missing the CLR assume that your app is targeting NET4 Client Profile by default (which should work out in most cases).­
