After compiling my VB app, and installing it on my machine, it will run. But, when I install it on my professor's machine at school, it doesn't work at all. What do I need to investigate in order to resolve this problem?
Visual Basic EXE files can't just be copied from one machine to another and work properly. You have to use the Packaging and Deployment Wizard (VB6) or the Setup Wizard (VB before 6.0) to create an installation package. That will package up all the required files so that the application can be installed on another machine.
