Hi Kalle,

That file is the VC8 C runtime "redistributable". It has to be in the 
same folder as your binaries or in your path. Depending on your version 
of VC8, you could have received the file when installing VC (it should 
be here:  \program files\Microsoft Visual Studio 
8\VC\redist\x86\Microsoft.VC80.CRT but this folder was omitted in the 
release version).

You could have got it when installing the .NET Framework (look here: 
\WINDOWS\WinSxS\x86_Microsoft.VC80.CRT_*). Its also contained in 
vcredist_x86.exe which is supposed to be here:
\Microsoft Visual Studio 8\SDK\v2.0\Bootstrapper\Packages\vcredist_x86\ 
... but isn't.

It seems you're supposed to install MSI3.1 to get the file now... look

Anyway, search your machine for this file and copy it to your VTK/bin 
folder.(*) Alternatively, compile a static VTK.
