Answer 1

Probably because you don't have the debug versions of the CRT libraries installed on the target machine.  You must deploy the Release build.

Answer 2

do you mean mfc80ud.dll, msvcp80d.dll and msvcr80d.dll?

i have copy them to the target machine.

i have to debug my app on the target machine, so i have to run the debug build.

Answer 6

Legally, you cannot run the debug version on a computer that does not have VS2005 installed. I'm not even sure there is a way to install the debug CRT libraries without installing Visual Studio.

I have searched for this kind of information for a long time. This is for Visual Studio 2010 "Determining Which DLLs to Redistribute": 

"You cannot redistribute all of the files that are included in Visual Studio; you are only permitted to redistribute the files that are specified in Redist.txt. Debug versions of applications and the various Visual C++ DLLs are not redistributable." (http://msdn.microsoft.com/en-us/library/8kche8ah(v=vs.100).aspx)

The problem is that there were no quoted Microsoft's sources for this kind of legal information. This question (asked often) was often answered with intro like IMHO, etc. Thus, you could decide whatever you like concerning software version redistribution.

See for example "Why is a bad practice to distribute the Debug version of the application in .NET?:http://stackoverflow.com/questions/5101458/why-is-a-bad-practice-to-distribute-the-debug-version-of-the-application-in-net/10071712#10071712
