Remarks:

  • You may have to install additional files for such Visual Basic application to work, such as OCX files for user interface controls.
  • Installation of the run-time files requires Administrator or Power User privileges. Use the Multi-User header file to verify whether these privileges are available.
  • Add a Modern UI finish page or another check (see IfRebootFlag) to allow the user to restart the computer when necessary.
