While regsvr32 tool is used to register COM servers, such as .DLL, .OCX, .AX files, sometimes you need an equivalent for type library files, such as .TLB, for example to automate software registration on a host. There has been no stock utility for this that I am aware of, so I have been using my own one (RegisterTypeLibrary):
C:\Program Files\Alax.Info\Media Tools>RegisterTypeLibrary.exe Acquisition.dll Type Library Information: File Path: Acquisition.dll File Full Path: C:\Program Files\Alax.Info\Media Tools\Acquisition.dll Name: AlaxInfoMediaToolsAcquisition Documentation String: Alax.Info Media Tools Acquisition 1.0 Type Library GUID: {4C03D3C8-13AD-451F-9363-FAD08EF94A91} LCID: 0 Platform: 1 Version: 1.0 Flags: 0x8 Registering... Registered.
/U unregisters, /Q displays information about type library (may be useful as it also works for .DLL files where type library is embedded into binary).
