Until that is fixed or Wizards changes the program, I'm not sure this app will ever work.

There is a "wide-beta" out now that will hopefully lead to working, but it still looks to rely on .NET.

Any luck getting this to work? I tried installing the .NET within WINE but it doesn't seem to make a difference.

Here is an article about .NET and Wine that may help.

I just installed Version 12.1.1 (12.1.1.26821) tonight, and installed the .NET 4.0 runtime.

Now when I try to install the MGTO wide beta (freshly downloaded tonight), it pops up a browser for the URL http://mtgoclientdepot.onlinegaming.wizards.com/MTGO.application, which google tells me is a ClickOnce Deployment Manifest for .NET. I'm guessing in real windows, opening a file of this type would trigger some installation program that's part of .NET.

Anyone know how to invoke that manually, or what other component(s) I might need to install?

According to this MSDN page, http://msdn.microsoft.com/en-us/library/bb892924.aspx, there's a program called Mage.exe that handles them. Maybe we dig a bit more into that?

It sounds like mage is for creating/editing the files, not opening them.

Windows has .application files associated with "rundll32.exe dfshim.dll,ShOpenVerbApplication %1". Does .NET 4 include dfshim.dll?

You're right. Mage was not the right call. This StackOverflow question confirms what you said, http://stackoverflow.com/questions/11833641/using-rundll32-exe-to-launch-a-click-once-deployment-url

And looking up dfshim.dll it appears that it has been around since .Net 2.0, so hopefully it gets installed with 4.0.

There is a problem with the .NET 4 installation process, specifically mscoree.dll is
removed and not updated to version 4.```
err:module:import_dll Library mscoree.dll (which is needed by
L"C:\windows\Microsoft.NET\Framework\v4.0.30319\mscorsvw.exe") not found

It will download after you install mscoree.dll, but the actual client will fail to  
initialize the MediaSystem subsystem and crash.
