Things to keep in mind.
WAMP is 32BIT, so you must install ColdFusion 9 32bit
Install WAMP – default c:/wamp
Install CF9 – default c:/coldfusion9
Directory of Server Binary
C:\wamp\bin\apache\Apache2.2.11\bin\httpd.exe (this worked for me for some reason)
This way you can go directly to localhost\CFIDE\administrator\index.cfm
That’s it, much easiler than SL & MAC.
