Getting MainEngineThread is returning 1603 when attempting to install SQl Server 2005 Standard Edition 32 Bit (5th instance)

I have a Windows 2003 host, 32 bit, and I have 4 instances installed, including default instance.

When attempting to install the 5th instance the install craps out with:

I am using a domain account, the same one that I used to install the other instances.  Could it be possible I am running out of memory?
I dont think that you are running out of memory.. check framework
