Install VBTRACE as follows.

1) Create a directory for VBTrace.
2) Unzip VBTRACE.ZIP into this directory.
3) Move SSDATA2.VBX to the Windows\System directory.
4) Move VBCTRL3D.VBX to the Windows\System directory.
5) Add VBTrace to a program group.

IMPORTANT NOTE: VBTrace requires that SSDATA2.VBX and
VBCTL3D.VBX be dated no earlier than the versions included
in VBTRACE.ZIP. Earlier versions will cause an 'Invalid File
Format' error.

The latest version of THREED.VBX, 3.0a, should also be used.
The version can be checked by adding THREED.VBX to the VB
toolbar, adding any of the THREED.VBX controls to form1,
and clicking on the About Box in the properties list window.
Version 3.0a may be downloaded from the Sheridan library in
the COMPA forum on Compuserve or from ftp.apexsc.com/pub/cgvb/coop/cstuart on the Internet.
