install cf9 32bits on Win 7 64bits

Is this possible ?

Installation of CF9 32 bits on Win7 64bits ?

I did it, with CGI and ISAPI for IIS7.

IIS 7 is OK, (http://127.0.0.1  is correct)

After CF9 install, I ran the WebServer ConfigurationTool

http://127.0.0.1 gives an error 500 :

then I uninstall C F9 , now I have a 404.2 error

I looked in install recommandation on the web (google).

I think I did the right way.

Then I am wondering if this is a question of 32bits and 64 bits ?

Thanks for urgent Help.

(I have an other PC with CF9 32bits on Win7 32bits, it is OK

and a CF9 64bits on Windows serveur 2008 64bits, it is OK)

Pierre.
