Running VB 6 on Windows 7 gives me this error. And many more related to dll's not loaded as a control class. What is frustrating is that I encountered this previously on another computer and resolved the problem. But I can't remember how.
Also, I don't need advice on using Visual Studio.Net instead. I use it for other projects, but my VB6 project is way too complex to convert or start over.
Class MSComctlLib.ProgressBar of control ProgressBar1 was not a loaded control class.
