Error while building VS2005 solution with VisBuild

[teognost]

Finally I decided to build the solutions under "Mixed Platforms" platform,so this way everything is ok (I am using MSBuild from VisBuild step).
After some tests I have seen I cannot build my projects using MSBuild.exe (I tested even from command line ,outside VBuild) under a platform different than "Mixed platforms"(Any CPU or Win32).
It seems to be a bug in MSBuild.exe.
When I called MSBuild.exe without platform parameter-still the "Mixed platforms" platform was used (as default) and this is why the building was succesfull.
I even tried to use devenv instead of MSBuild (in VisBuild step) but still the same -only Mixed platforms can be build.
Thanks for your help.
I guess you do not need to send those files anymore...
