Silent Hunter 5 and the .NET Framework 4.0

[Seeadler]

*Edit*

Thread title changed!

It's not the .Net 4.0 framework which is cause a CTD after loading in SH5, the new Visual C++ 2008 Redistributable 9.0.30729.4974 runtime files produce this error. These new runtime files could be installed be upcoming Windows apps! Thanks to SubV, who had found that!

Warning: Silent Hunter 5 is not compatible with the. NET Framework 4.0

Today I installed on my gaming/internet PC the new .NET Framework 4.0 because I had to test a .NET 4.0 application for one of my customer on the network and internet.

After the installation, each time SH5 crashes to desktop with an undefined error after the loading screen of a savegame or a single mission. The last thing I could hear was the click-click sound of the SH5 interface, then SH5 crashed. The SH5 museum worked as it should.

After the deinstall of .NET 4.0, SH5 runs again without this error! To proof I installed .NET 4.0 again and the crash to desktop was back, again deinstalled .NET 4.0 and the game starts after loading a game.

I guess it is the IronPython.dll which cause this error because it is also an interface for SH5 to .NET Framework, and this dll is probably no longer compatible with the v4.0 runtime of the Framework

The current IronPython package which is for .NET4.0 was released last month on April 12., perhaps the SH5 project must be compiled/linked with the current libs of this release. No idea whether the new patch also deals with this issue.

Strange, because I thought that all new versions of dotnet contained backwards compatibility for previous dotnet releases.

Do you get any particular errors with the CTD?

.NET yes, all my .NET apps works with also with this new 4.0 release but I assume the IronPython.dll or the IronMath.dll used by SH5 did not

The devs of IronPython released a newer version last month which has the compatibility with 4.0

IronPython 2.6.1 Final was released, supporting both .NET 2.0 SP1 and .NET 4.0 RTM.

No only the a windows message box which tells me that "Silent Hunter 5 no longer works"

Recently, I tried the new Visual Studio 2010 (which is bundled with .NET Framework 4.0 and updated Visual C++ runtime libraries).

I've got the same problem as yours, CTD when loading save game or starting a single mission. So I tried to investigate this problem and finally found what causes the CTD. It's not .NET 4.0 itself, but Visual C++ 2008 redistributable 9.0.30729.4974.

Uninstall it via Control panel, and everything will work fine again.

thanks for this info, I will investigate this at the weekend if some of my customers apps also installs these redistributables.

You are right, it's the Visual C++ 2008 Redistributable 9.0.30729.4974 that caused the crash. One of the Apps I had to test installed the new runtime files alongside to the .Net 4 framework.
