I played with Enterprise Library 6.0 Logging and Exception Handling Blocks by using VS 2012 and and adding references with Nuget packages. Everything seems to work fine. But when I tried to download the Enterprise Library binaries with the help of the supplied PowerShell script, I got this error:

The specified executable is not a valid application for this OS platform.

I got the same message when I executed the PowerShell via command prompt as well as Powershell Script. This is the entire message:

C:\Enterprise Library>powershell -File .\install-packages.ps1

Check the NuGet bootstrapper located at .nuget\NuGet.exe (i.e. c:\Enterprise Library.nuget\NuGet.exe). Also check that the full NuGet package manager is installed at %localappdata%\nuget\NuGet.exe . Can you run NuGet: %localappdata%\nuget\NuGet.exe? Maybe try to run a self update: %localappdata%\nuget\NuGet.exe update -self and see if that works.

Hi Team,

I'm also having the same issue while running Install-Packages.ps1 for Entity Library 6. As per your reply I tried to to run the Nuget.exe even that gives me the same error message:
The specified executable is not a valid application for this OS platform.

Please reply as soon as possible.

Thanks in advance

It sounds like there is a problem with NuGet.exe. Try uninstalling NuGet and re-installing the latest version: http://nuget.codeplex.com/releases/view/133091
