Unregistering an ActiveX Server

[Cabman]

I've created an ActiveX Server from a LabVIEW vi that I open up from TestStand then communicate with the Controls and Indicators through the "ActiveX/COM" interface. Before starting it I call the executable with "myvi.exe /RegServer" to ensure that it has been registered with Windows. Everything works fine from this point on.

My problem is that when I'm done I quit the application and unregister the executable with "myvi.exe /UnregServer". When I make the call I get the Windows error "Write permission to the Registry denied, LabVIEW Server not unregistered" However, it does seem to work as the server is unregistered. I know this because if I try to create a reference to the application I get a "Type library not found error"

I couldn't find anything on MSDN about this. If I try the same thing from the command prompt I still get the error.

It's probably not really necessary to unregister the server, but as I update it I don't want old unused registered versions showing up.

Any clues as to why I get the error?

Dave,
"My problem is that when I'm done I quit the application and unregister the executable with "myvi.exe /UnregServer".

I think that your problem may be that the command is "myvi.exe /UnregServ" (not /unregserver)

I don't think so. According to MSDN and The TestStand Reference Manual the syntax is /unregserver.

I tried ti with /unregserv and it just seems to ignore it and runs the executable. The server is still registered in the system.

Cabman -
I do not have any suggestions, but how did you attempt to create a reference to the application when you got "Type library not found error"?
