The ActiveX controls listed above are no longer supported, but ship with the
Professional and Enterprise Editions of Microsoft Visual Basic for backward
compatibility when upgrading existing projects.
These controls do not ship with the Learning Edition of Microsoft Visual Basic.
For the Professional and Enterprise Editions, the controls are located on the
installation CDs at the following locations:
Microsoft Visual Basic Edition Location
----------------------------------------------------------------------
Professional 6.0 \Common\Tools\VB\Controls
Enterprise 6.0 \Common\Tools\VB\Controls
Visual Studio Professional 6.0 \Common\Tools\VB\Controls (CD2)

Each of these directories contain a README.TXT with instructions on how to
install the controls for design-time use.
NOTE: Using the Learning Edition to upgrade a project developed in an earlier
version of Microsoft Visual Basic might result in licensing problems for these
controls.
The VBUSC.EXE installs the design-time licenses for the controls listed above if
Visual Basic is detected on the computer.
