iis 7 application pools not starting after installing ibm client access

A co-worker of mine is having an issue with our dev server after installing
IBM i Access 6.1.
http://serverfault.com/questions/486305/iis-7-application-pools-not-starting-after-installing-ibm-client-access

I have a windows 2008 dev/testing server setup for testing web apps. I just
installed ibm client access (v6r1m0) and after my reboot my sites now get a
503 service unavailable error.

My application pools will not start and I get the following in the
application logs: The worker process for application pool 'ASP.NET v4.0'
encountered an error 'Cannot read configuration file due to insufficient
permissions ' trying to read global module configuration data from file
'\?\C:\Windows\Microsoft.NET\Framework64\v4.0.30319\CONFIG\machine.config',
line number '0'. Worker process startup aborted.

I had everything working just fine until the ibm install

Thanks for any help you can give us.
