Hello Alex,
The 3D graph control is really an ActiveX control that is included with several different National Instrument software products. It was originally part of the Measurement Studio package which is why it still carries this name. Certain NI software products install evaluation copies of the control.
Do you have any other NI software packaged or drivers installed on the Windows XP computer?
From what I understand your XP computer does not have LabVIEW installed, and you are using an executable created with the LabVIEW application builder. If this is true, you will need to create an installer with the Application Builder, and in the Advanced dialog box ensure that the "3D Graph Support" is checked.
