CGI Error installing 2.7.1

The vaunted “5 minute installation” only took nearly 36 hours. Upon installing version 2.7.1 on IIS6, WordPress returns the nasty:

“CGI Error
The specified CGI application misbehaved by not returning a complete set of HTTP headers.”

This server is running multiple other PHP sites with no problems but after combing through all the posts, implementing all the suggested tweaks (all to no avail), I took another approach. I had to go back as far as ver 2.5.1, but finally found a version that installs properly and runs as intended.

If anyone has had success running 2.7.1 on IIS6, I would love to know how you got it to work.

Thanks!
