Visual Studio 2012 Beta - Error when deploying the app

I have installed Windows 8 OS RP version and visual Studio 2012 beta version. But i'm getting the following error when deploying the package.

Error:

Windows cannot install package xxxxx, because this package requires a higher Windows version. The package requested Windows version 6.2 with AppModel version 1, while the current Windows version is 6.2 with AppModel version 0. (0x80073cfd).

How can I resolve this issue?

Any help would be appreciated.

Thanks in advance

Did you try creating new project and the carrying old files to the new project?
