Hello all,
I am trying to get an application to load if a file type is clicked. I set up the open verb in the file type editor in and when I click on the type of file the program starts how ever I get a File not found error. The open verb on the file type seems to work since it first loads loader.exe which creates an appdomain for app.exe. But whe it trys to execute the domain an exception is thrown


Here is the function that creates the domain from loader.exe :

Public Sub start()

appSetUp.ApplicationBase = "file:///" & Application.StartupPath()

appSetUp.ApplicationName = myFileToRun
appSetUp.PrivateBinPath = Application.StartupPath()
appSetUp.ConfigurationFile = myFileToRun & ".config"
Dim adevidence As System.Security.Policy.Evidence = AppDomain.CurrentDomain.Evidence
domain = AppDomain.CreateDomain(myFileToRun, adevidence, appSetUp)
domain.ExecuteAssembly(myFileToRun, adevidence, myArgs)
Catch e As Exception
Dim sw As New System.IO.StreamWriter(System.IO.File.Create("D:/temp.txt"))
End Try
End Sub

Here is the exception :

System.IO.FileNotFoundException: File or assembly name app.exe, or one of its dependencies, was not found.
File name: "app.exe"
