Default COM Creation - Specified cast is not valid

Hello,

I have the following method to help me in installing some COM
components onto the machine...below is a snippet that is causing the
problem...


Code:
Type objType = null; 
COMAdminCatalog objCatalog = null; 
COMAdminCatalogCollection objApplicationsColl = null; 
COMAdminCatalogObject objApp = null; 
try 
{ 
                  objType = 
Type.GetTypeFromProgID("COMAdmin.COMAdminCatalog"); 
        objCatalog  = 
(COMAdminCatalog)(System.Activator.CreateInstance(objType));

It is part of setup application...so when I run the setup on my
machine, it works fine....


However, when I try to test it on one of our servers.....I get a
Specified Cast is Invalid exception from this line objCatalog =
(COMAdminCatalog)(System.Activator.CreateInstance( objType));


I am guessing its a problem with either one of the last two
line....forgive me, im new to COM


Thanks in advance
