R6034 from vanilla setup ?

I have delayed using Visual Studio 2005 until now because I didn't want to switch in the middle of a big project. I have a completely vanilla setup using every default option. My executable has two user-written DLLS. My first attempt at running in the debug mode raised this familiar error. I checked the properties and it is creating a manifest file and is embedding a manifest file (apparently the defaults). Why do I get a message about attempting to load the C Runtime library without a manifest I did try several solutions from reading different approaches such as copying the Microsoft.VC80.DebugCRT folder to the same folder that contains the ".exe" without success. But my question is more basic: Why do I get this message when I have generated the manifest as recommended. I also read postings that show how to duplicate the module built by the IDE, implying that Visual Studio builds the correct files. But I still get the message. Can you help

Thanks, Mark
