"405 Method Not Allowed" is most likely an IIS configuration issue. Please try reboot and try to redeploy again.
You need to check and ensure that both Roles and IIS components are installed correctly and that the HFM is functioning OK via IIS when browsing through it.
Also, by default IIS does not install ASP server scripting roles. To correct this by adding the ASP role in IIS
"If you are using Windows 2008, you must install ASP Role Services before installing EPM System products that require IIS. If you are using Windows 2008, you must install .NET 3.5 before installation of Data Relationship Management.
If IIS is chosen as the Web server during configuration, you must allow all unknown ISAPI extensions through the Internet Information Services Manager."
