Hello,

I have a new machine whith Windows server 2008 x64 and i installed on it CF8.01.
For installing, no problems and the service work fine.
But, when i launch one page on the web server, a .cfm or a classic html the IIS 7 return a error 500.21 :

HTTP Error 500.21 - Internal Server Error

In IIS config panel, handlers mapping, i have entry for all CF handler and one with path * and direct from jrun_iis6_wildcard.dll.

the section of web config for handlers is :
<handlers accessPolicy="Read, Script,Execute">
<clear />
<add name="AboMapperCustom-23790" path="*" verb="*" modules="IsapiModule" scriptProcessor="C:\ColdFusion8\runtime\lib\wsconfig\1\jrun_iis6_wildcard.dll" requireAccess="None" responseBufferLimit="0" />

</handlers>
and

Application 32bits mode is ok
