How to Register Msvcr80.Dll

DLL, or Dynamic Link Library, files contain programming language that can be used by the Windows operating system and third-party applications. Instead of including the same code in programs over and over again, the developers make applications compatible with DLL files. Msvcr80.dll, for example, is used by applications that run based on Microsoft Visual Studio 2005. If it's missing or corrupt, the programs using it won't function properly. You can download and install a DLL from the net, but you have to register it with the operating system to make it work.
