TBarCode V7 and all newer versions use the C/C++ Runtime Libraries from Visual Studio 2005 (CRT V8). The required files are installed by the TBarCode setup program automatically.
Although very often required, these libraries are not part of a Windows standard installation. But it is possible to install these libraries from an extra package available from Microsoft:
If you use an installer (e.g: Installshield or WIX) you can also include so called MSM modules, which contain these VC8/CRT8 runtime libraries. MSM modules (merge modules) are installed into the correct folders automatically by your setup application.
