As a first step ,make sure that you have the components installed on the machine.for example check the respective MIME type installed on your webserver.
If you are getting an error some thing like ” Description of HRESULT ISAPI filter “drive:\Path of file\ISAPI_FLT.dll” tried to register for SF_NOTIFY_READ_RAW_DATA notification” .
Because IIS 7.0 does not support the Internet Server API (ISAPI) filter that registers for the SF_NOTIFY_READ_RAW_DATA notification.
I added the .aspx extension in MIME Types, with text/html as the MIME Type. Even though I’d installed asp services, it didn’t put this type in IIS, so it was unrecognized.
