web installer

[slickgoonie]

Hello guys:

I've made created a installer modifying the nsis file, now, I'm trying to embed this installer into a cab file that will get executed through the browser, so the user doesn't have to install anything. This is what i have so far:

the .exe file
the .inf file.
the .cab file
the html for the activex.

What I need...is the CLASSID. I don't really know how to get this, how to generate this ID, or what this ID means for any case. Any help would be appreciated.
