I\'m experimenting with writing ActiveX controls and noticed that I can\'t seem to create an ActiveX control in Visual Basic (6.0) which features slightly more sophisticated
To solve this problem, I developed a .msi package. The source files (WiX) and stake posted here: https://github.com/IT-Service/ITG.VB6CommonControlsRedist
VB6 runtime is preinstalled on XP and above but the Common Controls component you are referencing is not.
Try installing Microsoft Visual Basic 6.0 Common Controls redistributable on the client machines or event better make a setup for your application.
Edit:
Opps, the link is for an update that does not install the OCXs if not already present. The only redistributable I find is a merge module for Windows Installer.
