91 Object reference not set to an instance of an object.


On my devolopment machine the following code works fine however when I create a setup file and deploy this app to another computer It throws an error.

I was wondering if someone could tell me why the error "91 Object reference not set to an instance of an object" is thrown from the following code and how I might be able to work around this issue.

         Dim strDatabaseLocation as string

        'get database location
        Dim dbLocation As Microsoft.Win32.RegistryKey

        dbLocation = Microsoft.Win32.Registry.LocalMachine.OpenSubKey("SOFTWARE\\Bussiness\\Product", False)
        strDatabaseLocation = dbLocation.GetValue("Database location")

Any help would really be appreaciated!

The problem is u have not created the Registry key on the machine where u r deploying the code.

Check for the Key - SOFTWARE\\Bussiness\\Product
and Text u r opening - dbLocation.GetValue("Database location")
