Some of my programs run on Windows without any special prerequisites.

But others (like Data Mapper) require these prerequisites:

1. Microsoft Visual C++ 2008 SP1 Redistributable Package
2. Microsoft .Net Framework 2.0 or later
   I suggest you download:  Microsoft .Net Framework 3.5 SP1 or later

Here are some links to download these prerequisites from Microsoft’s website:
