how long to wait on 9.2 bitrock installer?

I have several versions of PostgreSQL already installed on this machine. We need to test compatibility with PostgreSQL database systems with our products.
I tried to install 9.2 64 bit using the one click installer from this location:
http://www.enterprisedb.com/products/pgdownload.do#windows

I did use an unused port of 5439 as 5432-5438 are already in use by other instances of PostgreSQL.

I am stalled here for more than one hour:

Is there any chance that the installer is still doing something useful, or do I need to kill the process and wait until the installer gets stabilized?
