PRB: Visual Basic Program Does Not Run on Other Computers

• Standard, Professional, and Enterprise Editions of Microsoft Visual Basic, 16-bit and 32-bit, for Windows, version 4.0

SYMPTOMS

A Visual Basic program runs properly on the development computer. The executable file, along with the associated control (.OCX) and .DLL files, are copied to another computer. Attempting to run the program on the other computer results in the error 424 with the following message:

   "You do not have an appropriate license to use functionality"

CAUSE

• The controls or DLLs used by the program were not registered in the system registry of the other computer.
• Some controls used by the program require dependency files that need to be installed and registered in the other computer.
• Some files, such as those for JET, are required to be in specific directories.

WORKAROUND

Use the Setup Wizard in Visual Basic to create an installation program that copies all the required files to the correct locations and makes the proper registry modifications. To install the program into another computer, use the installation program and the compressed files developed using Setup Wizard to properly install the program.

STATUS

This behavior is by design.

MORE INFORMATION

Visual Basic version 4.0 uses substantially more OLE components than version 3.0. These components have dependency files and require system registry modifications. Even if another setup program is used, Setup Wizard should be run on your application to allow the Wizard to determine all the necessary files needed by your program.

To reduce the number of required program files, remove unneeded controls from the project in the Custom Controls dialog box by following the steps below:

1. From the Tools menu, click Custom Controls, or press CTRL+T to display the Custom Controls dialog box.

2. In the Custom Controls dialog box, clear the checkboxes of the unneeded controls. Click OK to close this dialog box.

3. From the Tools menu, click References to display the References dialog box. Clear the checkboxes of the unneeded controls. Click OK to close this dialog box.
