When using MSVC 2008 you need to include the following files in the same folder as your exe:

Microsoft.VC90.CRT.manifest
msvcm90.dll
msvcp90.dll
msvcr90.dll

Then distribute your app with an installer. I suggest Inno Setup (http://www.innosetup.com/isinfo.php) which is fairly easy to learn to/and use.

You should be good now.
