How to register DLL files in Windows 7
The command to register the files manually is called regsvr32. Now let’s take a quick look at the syntax of regsvr32:
/u Used to unregister DLL files
/s If you don’t want any dialogs you can use the “s” for silent option
/c Get the console output
/n Register DLL file without DllRegisterServer
/i Register DLL file with DllInstall (or DllUninstall if /u is specified)
DllInstall is used only for application installation and setup.
Manually Register DLL files via Command Prompt
If you successfully re-register a DLL file, you should get a message like this one:
DllRegisterServer in shell32.dll succeeded.
