The problem is that your native C++ DLL depends on the library msvcr71.dll. This is not part of the standard windows installed hence you must take some action to get it onto the target machine.

The simplest way to do this is to just copy the DLL around with your application. The following KB article covers this.

Documentation on msvcr71.dll

You're probably missing something in your installation of the SDK (or Visual Studio). I would recommend a Repair or Reinstall.

look on msdn for info about redistributables - this tell you what you need to install on a non dev box to make things work

This is not programming related. You are missing a dll file on your target system. Download and put in "windows/System32" and it should run.
