.NET Forum / .NET Framework / Interop / April 2007Regasm /regfile attribute lies?
I have an Office Add-In that I am distributing and installing. When I run Regasm /regfile on it, and then double-click the resultant regfile (adding it into the registry) my Add-In does not appear in the list of available automation servers on the machine. However, if I call Regasm on it, it then does appear in the list of automation servers. This indicates that Regasm /regfile does not put into the reg file the same thing that regasm is doing. Running regmon turns up that while Regasm /regfile puts several keys into HKCR, actually calling Regasm, puts many of those keys into HKCU. Can anyone explain? Regasm /regfile does not create type library registration entries - that's probably what's going on because a list of available COM servers is typically a list of type libraries.

One way to see this list, is to open Excel (XP or 2k3), click on Tools->Add-Ins and then click on "Automation".

You may have done a "Just me" install instead of Everyone. In a VS 2005 setup&deployment project, that's the InstallAllUsers property to set the default at per-machine (Everyone). With my COM hat on, this is my understanding. Any correction welcome. Automation Servers are COM servers that offer interfaces for script clients. The list is typically generated by enumerating those classes with some set of scriptable component categories (OleView shows the general idea), and then locating the type library. It's equivalent to a C# project where you Add Reference and choose the COM tab - the list you get is type library-based, and Automation Servers are a subset of those. -- Phil Wilson [MVP Windows Installer] > no tlb is generated , also, the list is of "Automation Servers" not COM > servers.
