Problem with Boostrapper and IIS6

I' m trying to deploy my ClickOnce app to a client without Framework 2.0 installed so I want the bootstrapper to deploy the Framework 2.0 to my client.
My problem is this: when deploying to a client with the framework 2.0 installed using the link 'launch' on the vs2005 generated web page everything goes fine (I already setted correctly the MIME types in IIS) but when attempting to use the 'INSTALL' button that links to the vs2005 generated setup.exe it returns http error 404.
I think IIS do not allow access to .exe files, so must I set another MIME type( and if yes what is the correct setting?) or I missed something else?
Thank You
