title: Task could not find "AxImp.exe"
body: <p>I uploaded a .NET 4 C# solution to appharbor, however when appharbor tries to build it, one of the c# class libraries generates this error:</p>
  
  <blockquote>
    <p>Project
    "D:\temp\cbymsn2u.j0c\input\UI\Tray\Tray.csproj"
    is building

    warning MSB3084: Task attempted to
    find "AxImp.exe" in two locations. 1)
    Under the "C:\Program Files\Microsoft
    SDKs\Windows\v7.0A\bin\NETFX 4.0
    Tools\" processor specific directory
    which is generated based on
    SdkToolsPath 2) The x86 specific
    directory under "C:\Program

    to solve the problem by doing one of
    the following: 1) Set the
    "SDKToolsPath" property to the
    location of the Microsoft Windows SDK.

  <p>There don't seem to be any different references in Crawler.csproj so where would this error come from? The same code builds fine locally.</p>
