PostgreSQL 8.1.4 install failure on Win XP Home laptop

I've searched the archives and found no helpful info, so I'll ask here.

I've successfully installed v8.1.3 on my laptop and was attempting to upgrade it to version 8.1.4 when I ran into the
messageindicating that the service could not be installed due to insufficient permissions to install services.  The
actualmessage was: Service "PostreSQL Database Server 8.1" (pgsql-8.1) could not be installed.  Verify that you have
sufficientprivileges to install system services. 

After I received the message, I attempted to install (and remove) other services I've written.  I was able to install
andremove these services without issue. 

I just double-checked and the account I'm signed in under has administrator privileges (the only account on the laptop
thathas such).  The only catch I can think of is that its name is not "Administrator".  I've encountered other software
thatrefused to install if the account name was not "administrator" (regardless of actual privileges).  Is this now the
casewith postgresql?   

Any suggestions?

Thanks, in advance,

Gord
