Download source for mscomctl.ocx ?

[Nomen]

Windows 7, 32 bit.  I'm trying to run a program and it's throwing up a runtime error 339 and saying something about mscomctl.ocx either missing or not being registered.  I apparently don't have this file on my system.  Is mscomctl.ocx normally found on a win-7 system (that does not have office or visual studio) ?  Does MS make this file available for download?

It is likely this one, Visual Basic 6 Common Controls. It indicates that the program you have was written for XP or earlier OS.

The system requirements do not even list Windows 7. I don't know if the software will actually install. The file just needs to be in System32 OR (more responsibly) in the working dir of the .exe you are trying to run.

I was looking at this DIAX soft-phone:

Specifically, diax0915a.zip - the current version.  The program file (diax.exe) seems to be dated to June 2005.  I tried changing it to run under XP-SP2 compatibility, but got the same error.

The issue here may be that the "whole" VB6 subsystem is needed.

If only mscomctl.ocx is needed, you can get it from here:

and extract it manually with - say - 7-zip.

The .ocx will probably need to be registered, using regsvr32 or regdllview (GUI):
