[HELP] Visual Basic 2008 Error
Warning 1 The "GetWinFXPath" task could not be instantiated from the assembly "PresentationBuildTasks, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35". Please verify the task assembly has been built using the same version of the Microsoft.Build.Framework assembly as the one installed on your computer and that your host application is not missing a binding redirect for Microsoft.Build.Framework. Unable to cast object of type 'Microsoft.Build.Tasks.Windows.GetWinFXPath' to type 'Microsoft.Build.Framework.ITask'.
Warning 2 The "GetWinFXPath" task has been declared or used incorrectly, or failed during construction. Check the spelling of the task name and the assembly name.
What were you trying to install? Microsoft itself was notified of the issue, it seems to be compatibility of .net framework (example 2008 3.5 to 2010 4.0 to Vb to C#)
so really, we need to know what steps you took that lead you to this error.
