Running rgsvr32 in program files\myapp seems to fail even when run as admin

Question

Our software needs to be able to register an ocx at runtime. The OCX lives in the program files directory of the app. I find that if I manually fire up a cmd line as admin and run the command everything works great, however if i fire up our app as admin and let the app try to register the ocx, it fails. I also notice that the app is able to run regsvr32 successfully when i run it from my build directory, presumably because i own the build dir. I still have to run as admin though. Anyone have any ideas what could be going wrong?

Thanks, brian

Answer 1

The answer is firstly, that i'm sloppy, and secondly that the command line args passed into regsvr32 need to be wrapped in double quotes. It never occurred to me because i wrote my code like so:

string args = "/s " + Path.Combine(MP_xxxx_DIR.FullName, MAP_POINT_OCX) ;

when it should have looked like:

string args = "/s " + "\"" + Path.Combine(MP_xxxx_DIR.FullName, MAP_POINT_OCX) + "\"";

Hope this helps someone else :)
