[Mono-list] Application installation on Windows

[Alexander.Nolting at Bertelsmann.de]

Hello Robert and also Andreas,

I took some thoughts since my question and I think you both on the right way. For is interesting to install a .NET app on a linux os. My idea is now to use wine and mono together, in fact using wine to handle the msi packages by installing windows installer under wine and then the needed apps. Then has to be a script in the msi which determines where mono in which version is installed and provide a bash script in the install folder of the msi, which also find out where mono is installed and starts the app in the right way (mono <app>|<path with app>).

regards
Alex

That's quite easy:

1) lookup the string value

    $version = HKLM_LOCAL_MACHINE\Software\Novell\Mono\DefaultCLR

2) lookup the string value

     $monoprefix =

HKLM_LOCAL_MACHINE\Software\Novell\Mono\$version\SdkInstallRoot


3) (optional) detect whether $mono-prefix\bin\mono.exe exists.

If one of the steps above failed, Mono is not properly
installed or too old.

Usually the tool (1) which generates the MSI is able to create
icons almost automagically.

The shortcut target is

	$monopath\bin\mono.exe

The shortcut's command line

	$installdir\yourapp.exe

The shortcut's icon

	$installdir\yourapp.exe


(1) I can't really recommend one, but have a look at WiX:

	http://wix.sourceforge.net/

Despite of its very misleading name (for Germans ;-),
it's a nice toolkit.

This can't be provided, because this would require that
MS.NET is installed on the machine. Otherwise the MSI engine
won't be able to execute the custom actions implemented
by your assemblies.
