Dumpbin /imports

Copying dlls is not recommended, because of possible additional
dependencies. There is a VC runtime installer called vcredist.exe that you
can scrap from msdn.microsoft.com.
If the going really gets tough, especially with old Win9x systems, I always
recommend to install IE 5.5, even if you never use it.
