Accessing WindowsControlLibrary dll from GAC

Is there a way to access WindowsControl Library from internet explorer
in GAC?
I need to write simple plugin which should start some simple exe file.
If my dll is stored on intranet I will not have enough permissions to
do that(start exe), but if my dll would be in GAC it would work.
(Clients would simply have to install it through some installation
program which they would have to download and start)
So what I need is instead of having

classid="WindowsControlLibrary1.dll#WindowsControlLibrary1.ExeStarter
in my object tag
I need it somehow to point to GAC -dll


Thanks in advance
Almir

original object tag:
<OBJECT id="simpleControl1" name="simpleControl1"
classid="WindowsControlLibrary1.dll#WindowsControlLibrary1.ExeStarter"
