Question:

How can I register (install) a DLL on Windows from the command line?

Answer:

It is possible that your application requires this DLL to be on the search path. In this case you could move it to \Windows\System32
Or the application requires it to be in the application directory.

Now to register it, you need to move to the directory where the DLL is located and use the commandline tool RegSvr32. This tool should be on your search path (in \Windows\System32).

At the command prompt do the following:

// to register it:
regsvr32.exe  MyLibrary.dll


// if you don't like the dialog box popping up afterwards:
// option /s means 'silent'
regsvr32.exe /s MyLibrary.dll


// if you want to unregister (uninstall) it later:
regsvr32.exe /u MyLibrary.dll

// silent version
regsvr32.exe /u /s MyLibrary.dll

to: kovacsio@hotmail.com - lols. its wrong. you need to copy first the dll in put it in the system 32 before you try to register it. Aa what the delfhinfaq said 'Now to register it, you need to move to the directory where the DLL is located and use the commandline tool RegSvr32. This tool should be on your search path (in \Windows\System32). ' the sentence is so clear 'This tool should be on your search path (in \Windows\System32). '

anonymous: 'the sentence is so clear 'This tool should be on your search path (in \Windows\System32). ''
i'm sorry to say that, but - you are wrong. The Tool regsvr32 is supposed to be in windows\system32\, that's why they say 'This tool should...' the dll can stay whereever it is.
makes no sense to copy the dll to system32 and registering it from here, because if you copy the dll back to its location, windows won't find it, because you only registered a dll in 'system32'
kovacsio must have a different problem.

I've searched far and wide for a solution to just such a problem: my SwPrv.dll exists in the system32 directory, but apps that require it to function (e.g. Backup in Windows Home Server), can't trigger/use it...

How the hell do I get it to function?

i think your problem might be b/c dos doesn't reconize spaces so the file location is invalid
