PRB: "License Information for This Component Not Found" Error

• Microsoft Visual Basic Control Creation, Learning, Professional, and Enterprise Editions for Windows, version 5.0

SYMPTOMS

When you try to add a control to a form, the following message may appear:

   License information for this component not found. You do not have
   an appropriate license to use this functionality in the design
   environment.

CAUSE

When a control is installed for run-time use only (such as those installed by an application created with Visual Basic), if the Visual Basic Development Environment is installed onto the same machine afterwards and the existing control is of equal or higher version than that from the CD, the license key for that control is not updated.

RESOLUTION

If the control in question is any of the ones listed below, then find the file Vbctrls.reg in the VB5.0\Tools\Controls folder on the Visual Basic CD- ROM and double-click the file:

   AniBtn32.ocx
   Gauge32.ocx
   Graph32.ocx
   Grid32.ocx
   KeySta32.ocx
   MSOutl32.ocx
   Spin32.ocx
   Threed32.ocx

If the control in question is not among the controls listed above, please do the following:

1. Locate Regsvr32.exe on your machine. Note its path.

2. Locate the offending OCX file(s), usually found in the Windows\System folder for Windows 95 or Windows\System32 folder for Windows NT.

3. On the Start menu, click Run.

4. In the Run dialog box, type the following:

         <Path to RegSvr32>\REGSVR32.EXE /u <Path to OCX>\OCXFILE.OCX
   

   For example:

         C:\Devstudio\VB\REGSVR32.EXE /u C:\Winnt\System32\COMCTL32.OCX
   

   NOTE: If Regsvr32.exe is in the System or System32 folder, the path is optional.

5. Repeat steps 3 and 4 for each offending OCX.

6. On Control Panel, click Add\Remove Programs.

7. Select Visual Basic, and click Add\Remove.

8. Click Reinstall when the options (Add\Remove, Remove All, Reinstall) dialog box appears.

MORE INFORMATION

Steps to Reproduce Behavior

1. Set up a Windows 95 or Windows NT machine, Machine A, without Visual Basic 5.0 installed. Then set up a development machine, Machine B, with Visual Basic 5.0 and Service Pack 3 installed.

2. On Machine B, create a Standard EXE project. Form1 is created by default.

3. Add the following component (OCX) to the Toolbox:

         Comctl32.ocx
   

4. Add at least one control from this OCX to Form1.

5. Compile and save the project.

6. Create a setup application using the Visual Basic Application Setup Wizard, selecting all default options.

7. Install the application onto Machine A.

8. Install Visual Basic 5.0 on Machine A.

9. Start a Standard EXE project and add Comctl32.ocx to the Toolbox.

   Try to add any of the controls from this OCX, and this error message appears:

         License information for this component not found. You do not have an
         appropriate license to use this Functionality in the design
         environment.
