--- Comment #2 from Graham Inggs graham@nerve.org.za 2012-09-07 02:37:24 CDT --- Thank you for your suggestion. I tried 'winetricks dotnet20' and rundll32.exe no longer crashes, instead I get a message that this application requires .NET Framework 2.0 SP2.
I then tried 'winetricks dotnet20sp2', but I still get the message as above.
I also tried installing the Security Update for Microsoft .NET Framework 2.0 Service Pack 2 on Windows Server 2003 and Windows XP ( http://www.microsoft.com/en-us/download/details.aspx?id=29401 ), but that resulted in hotfixinstaller crashing in a similar way to rundll32.exe.
