I installed VB.NET 2010 Express and converted the program. It gave me many errors but they are all fixed now. Apparently I'm sloppy with my constant declarations because I had a number of them that had to be cleaned up. A lesson learned. Anyway, I loaded the installer and converted that too, but it doesn't want to work. In the solution explorer, it says "application is not installed". Can VB.NET 2010 Express make executables or do I need to buy a copy?
