< Installation - CODE/400; WebSphere Development Studio foriSeries >

I have a question, that I can't seem to figure out the answer for:

Environment:        CODE/400 v5r1
                        PC OS:  Windows 2000 Professional
                                Windows XP Professional

Question(s):
Background:
I have attempted to install the product (WebSphere Studio for iSeries; 
v5r1) on an installation of Windows XP Professional.  I keep getting the 
error: You must be signed on as Administrator or with Administrator 
privileges.  I am the administrator for the PC, and I've also signed on as 
"Administrator"; to no avail.  I can't seem to get past this message.  I 
would prefer to eliminate my Windows 2000 Professional partition so I 
could have one seamless OS on my PC for me to perform my work.

Question:
Is there a patch for SETUP.EXE; something I need to do in Windows XP 
Professional; or something else I'm missing?

Thank you for any assistance you can provide.
