FIX: GPF Occurs When Starting Visual Basic 5.0

 Last reviewed: December 18, 1997
Article ID: Q167346
The information in this article applies to:
  • Microsoft Visual Basic Control Creation, Learning, Professional, and Enterprise Editions for Windows, version 5.0

SYMPTOMS

When Visual Basic starts and the IDE is displayed, a GPF (General Protection Fault) occurs and Visual Basic does not load.

CAUSE

This problem may be caused by faulty Visual Basic 4.0 add-ins or invalid command bar configuration information in the system registry.

RESOLUTION

To prevent add-ins from being loaded when Visual Basic starts:

  1. Start Notepad.exe.

  2. Edit the VBAddin.INI file in your Windows directory and set all of the entries to zero (0). For example: 

        - Original:   AppWizard.Wizard=1
    - Modified:   AppWizard.Wizard=0

  3. Save VBAddin.INI.

  4. Restart Visual Basic.

To deduce which add-in is causing the problem:

  1. Click on Add-In Manager.

  2. Check a single Add-In and click the OK button.

  3. Restart Visual Basic.

  4. Repeat this process until Visual Basic produces a GPF.

  5. The last Add-In checked before Visual Basic produces the GPF is the faulty Add-In. You should remove the Add-In from your system and follow the instructions in step 1 above to remove the entry from the VBAddin.INI file.

To fix invalid command bar references in the registry:

  1. Start Regedit.exe.

  2. Delete the following key:

    HKEY_CURRENT_USER\SOFTWARE\Microsoft\Visual Basic\5.0

  3. Close Regedit.

  4. Restart Visual Basic.
