Project Upgrade to 2008 Vol.1 (3.5) not working
posted

I've tried upgrading a project that was using 2007 vol 3 (2.0) to 2008 Vol 1 (3.5) and I'm getting the error message:

 "Object reference not set to an instance of an object"

and then the upgrade window closes. Any ideas?

 

thanks.

    As far as I am concerned, I have the following unhandled exception:

     System.FormatException: Le format de la chaîne d'entrée est incorrect.
       à System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal)
       à System.Number.ParseDouble(String value, NumberStyles options, NumberFormatInfo numfmt)
       à System.Double.Parse(String s, NumberStyles style, NumberFormatInfo info)
       à UpgradeToolBase.RegBrowser.CreateVersion(String parentName, String keyName, String installDir, String clrVersion)

       à System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
       à System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

    "Le format de la chaîne d'entrée est incorrect" means "String format incorrect".

    When I click on continue, I have the GUI of the application, but I am not able to select a target version as this part of the GUI is missing.

     Is there another way to upgrade?

     Thanks.
