I found the problem.... When you want to "import" the com+ components from the windows component services manager, you need first to build manualy the applications and then add the the components.
The problem happened because I added one component (dll) not from the place where it should have been installed to on the destination machine, but I added it from the place I hold the files to be copied and installed in the destination machine.
For example: If I hold the files on c:\setup files, but the specific dll should be installed to c:\my components on the destination machine, I should add it on my(!) pc from c:\my components to the components services apllication I built first, and only then perform "refresh from system" in the "component services" manager in the DevStudio.
