The dependeny tracking works now, so you have only to select the 
requested kde.. package. all required packages are selected 
automatically when  confirm installation.

This will work for mostly cases and i will see, if I can add this to the 
installer. There is only one issue with using these environment 
variables: They are only available if the user logged out or rebooted 
his pc after msvc installation.  This could be fixed by using a registry 
key insted of the environment variable.

In HKEY_CLASSES_ROOT\Installer\Products\ there are all installed 
products listed

visual Studio C++ 2000 Expression Edition - ENU.
key = 9BA4F6BA58CA200489926BEE5AA53E5A
    PackageCode = A5941EA0844828F4B8E1999934548849

similar for visual Studio C++ 2000 Redistributable
key = b25099274a207264182f8181add555d0
    PackageCode =  ECF0C5769D85D534A98DCACD5B08A8A3


Microsoft Platform SDK (R2) (3790.2075)
key = E10DE0A981DFA754BAC98053CDBD71BB
    PackageCode = A5D5F0B4B5E72B74BAD850CC3E4A7889

Does anyone know if these keys are unique and are always the same ?

If you choose an installation dir where no packages are installed you 
have the choice to select mingw or msvc compiler. If only one package is 
installed this option is disabled to avoid corrupted installation dirs.

Thanks for this hints.
