The core component of Ranorex is a C++ Library, the RanorexCore.dll. RanorexCore.dll only dependents on the following 8 Windows libraries: USER32.DLL, KERNEL32.DLL, GDI32.DLL, OLE32.DLL, OLEAUT32.DLL, OLEAUT.DLL, OLEACC.DLL, ADVAPI32.DLL. All of these libraries are part of the Windows operating system.

Ranorex usually runs in the process space of a separate test application (like in the picture above), however Ranorex can also be embedded in applications.
