Visual Basic 6 - Possible Registry problem

I have installed VB6 on a Dell Inspiron 3800 laptop running Windows NT4 3 times.

When I try to open the component manager from the Project menu I get the following message;

'System Error &H80004002 [ -2147467262 ] no such interface supported'

So therefore none of the controls (apart from those in the standard toolbox )  are available for selection.

Can anyone help me solve this please?

Many thanks

PRB: System Error "No Such Interface Supported"
Last reviewed: December 31, 1998

The information in this article applies to:
Microsoft Visual Basic Learning, Professional, and Enterprise Editions for Windows, version 5.0

When you show the Components dialog by either right-clicking the Toolbox or choosing the Project menu, the following error message appears followed by a blank dialog box:

   System Error &H80004002 (-2147467262)
   No Such Interface Supported

Note that the memory address may vary.

This error is caused by an incorrect version of comcat.dll.

To resolve the problem, install the correct version of comcat.dll by completing the following steps:

Use REGSVR32.EXE to unregister COMCAT.DLL. REGSVR32.EXE is installed by Visual Basic or it may be found on the Visual Basic installation CD-ROM.
To unregister, select Run from the Windows Start menu, type the

following command line and
   click Ok:

      regsvr32 /u comcat.dll

Copy comcat.dll, version 4.71 (22k), from the ..\DevStudio\VB\Setupkit\kitfil32\sys32 directory or from your Visual Basic CD to the Windows\System or WinNT\System32 directory.

Use REGSVR32.EXE to register COMCAT.DLL. To register, click Run on the Windows 95 Start menu, type the following command line, and the click OK:

      regsvr32 comcat.dll
