How to install and register a DLL on users machine needed to app runs?

Hi Experts

I need to install and register a DLL on users machine needed to run a C# app I'm distributing.

I'm using NSISW installer.

Could you point the better way on doing that ?

Programatically? when the app starts it check if instalation is needed?
NSISW has a feature to do this?

Thanks in advance.

Hi

I need to use a component very specific to read a .DBF via Oledb file, just one time when the app starts, to authenticate the user.

 lcConnectionString =
                        "Provider=vfpoledb.1;Data Source="
                            + "c:\\xxx\\xxx\\B_xxx.DBF;Collating Sequence=Machine;";

Open in new window

So vfpoledb.dll is the DLL that must be registered.

Unrelated comment: You're hard-coding the database location as opposed to a registry entry or an XML/INI file?

Non-administrative users cannot register DLLs, so unless your application specifically requires local administrative access, your application may not work if the DLL truly needs to be registered.

Have you looked at Registration-Free COM objects?
