License Errors in VB4

License Errors in VB4

I ran across an interesting problem trying to install VB4 EnterpriseEdition in the Windows 3.1 environment. The new version of VBuses the Registry database, which in Win 3.1 is limited to 64K.As a computer consultant with a big-six firm, I have an extensivelist of software installed on my laptop to work in various clientenvironments. I had previously installed Microsoft Office, MSProject, and the standard Lotus Suite software. The REG.DAT filewas apparently just about maxed out. When I installed VB4, I gotno indications of errors during setup, but when I tried to runVB and use certain custom controls, I got “License”errors. A call to Microsoft verified the problem and brought thisworkaround:

  1. Manually remove VB4.
  2. Manually remove all OCX’s and OCA’s from windowssystem.
  3. Manually remove OC25.DLL from windowssystem.
  4. Rename Reg.Dat to Reg.Old.
  5. Remove all items from the Windows Startup Group.
  6. Remove all programs auto started in the WIN.INI file withthe
    “Load” or “Run”sections.
  7. Remove all TSRs from the Autoexec.Bat file.
  8. If you are running a compressed drive, free up 6MB of spacein a non-compressed volume.
  9. Exit Windows and reboot.
  10. Start up Windows and re-install VB4.
  11. Restore system settings.

Technical Reviewer’s Note: The license errors happened to mein Windows 95. An uninstall of VB and reinstall of VB correctedthe problem. Thanks for the tip!
