-first i installed cfmx as standalone
-then i manually added the mappings on iis
.cfm -> c:\CFusionMX\runtime\lib\wsconfig\1\jrun.dll (all)
.cfc -> c:\CFusionMX\runtime\lib\wsconfig\1\jrun.dll (all)
.cfml -> c:\CFusionMX\runtime\lib\wsconfig\1\jrun.dll (all)
.jsp -> c:\CFusionMX\runtime\lib\wsconfig\1\jrun.dll (all)
.jws -> c:\CFusionMX\runtime\lib\wsconfig\1\jrun.dll (all)
-copy the folder cfide from c:\cfusionmx\wwwroot\ to c:\inetpub\wwwroot
-then you must create the folder c:\CFusionMX\runtime\lib\wsconfig\1\, wich contains jrun.dll.
To do this i copied this folder from a different installation of cfmx on a different computer under a different OS (XP pro)
-on the iis management console, right click on 'name_of_the_computer'(local computer), and go to Security. On the wizard, on ISAPI handlers, you should enable C:\cfusionmx\runtime\lib\wsconfig\1\jrun.dll.
-restart everything, and done, ColdFusion on IIS 6.
