When installing and/or upgrading to Visual Studio 2012 RTM on a Windows 8 RC box, the installer may hang and inform you that you do not have .Net 4.5.x installed.
You cannot proceed until you resolve this.
- Windows 8 RC (Release Candidate/Preview)
- Visual Studio 2012 RTM
The problem is VS 2012 is not compatible with Windows 8 RC. If you attempt to download the current version of .Net 4.5 you will see this error:
This is because .Net 4.5 is integrated with Windows 8; there does not appear to be a way to manually upgrade your .Net version.
The only workaround is to upgrade your Windows 8 installation to the RTM version or later.
