I have a speed-reading program I purchased with uses dotnet2. However, dotnet2 doesn't run on 64 bit wine. How would I install dotnet2?

You can have multiple wine prefix on your machine, each running as a separate wine. So you can make a 32 bits prefix and install dotnet2 in it:

This will create a new wineprefix (.wine32 in your home) and configure it as 32 bits:

WINEARCH=win32 WINEPREFIX=~/.wine32 winecfg

You can use it this way combined with winetricks to configure WINEARCH, create the prefix and install dotnet 2.0 in one command:

env WINEARCH=win32 WINEPREFIX=~/.wine32 winetricks dotnet20

or only:

env WINEPREFIX=~/.wine32 winetricks dotnet20

if you already set the WINEARCH and created the WINEPREFIX with the 1st command above.

    Thanks. . . How would you install the program to that prefix?

    If the program has an uninstall, you can run it the same way. If not... you can remove the directory (or the files) where your program is installed (~/.wine32/drive_c/Program Files/your_program or something similar)

    @laurent dotnet2.0 is failing to install. It keeps asking if I want to send the report to Microsoft.

just to make it more straightforward to use wine in 32bit mode. Create a file in ~/bin/wine32 with the following content

env WINEARCH=win32 WINEPREFIX=~/.wine32 wine $*

Make the file executable to launch wine in 32bit mode using

wine32 my_exe_file_that_needs_32bit.exe

Hope that helps :-)

    Rather than making a script in ~/bin (which I think is a security problem anyway), you could make a bash alias in ~/.bashrc. Just take the same line from the script and put it in a line in .bashrc like this: alias wine32='env WINEARCH=win32 WINEPREFIX=~/.wine32 wine $*' May 18, 2015 at 16:57
