windows regsrv32

[Karttik]

Hi, i have no idea how exactly this process work. When i successfully registered dll library, i have not seen any change. I try register dll, what is already registered, what make this process when
1) current library has the same version, but another path?
2) current library has newer version
3) current library has older version
Registry changes should be immediate or take effect after restart?
It depends if the library is currently used?

regsvr32: The tool is to load the specified activex dll and call its DllRegisterServer, or DllUnregisterServer when /u key specified. Again, the activex code actually does all registration, and the tool just loads the dll and calls its functions. The tool never bothers about version and path, it just makes appropriate changes in the registry keys the server internals refer to. As any other registry changes, those are applied immediately.

In addition to what Igor said, registering 32bit COM objects on 64bit systems may store the registry settings in different locations.
