[@Bob] Thanks for including how you resolved the issue. I have a few guitar interfaces plus whatever Dell added to my PC for sound, and it gets confusing how to make audio work at times.
[@Dave Cole] I already had version 1.21.1 installed (and highly recommend it!). So I can’t address registration issues I don’t remember. When I run the program, a window pops up with choices for record mode (web page, game, etc.) I normally pick “Capture online video”. Then I get the program’s window, what I think you call the Control Panel (big red record button, screen size, pause, close, settings, screenshot, etc.) This can be minimized to system tray (click the “_” button to the left of the “X” close/exit button) and you can also move it to different places if you want (click & hold in green timer section, drag it where you want, release mouse buttton). If you “close” the program, it exits altogether so no, there will no longer be an icon in the system tray. Just start it again when needed. Recording can be started and stopped with definable hotkeys if you don’t like to see Control Panel. If Control Panel is minimized, double-click the circular red & white button in the system tray (single-click doesn’t always work). Right-clicking that button also brings up a nice menu which includes “About”, where it looks like you would enter registration information.
This really is an excellent program. ZD Soft has done a good job of making something that works well, does most of what you need, and pretty much can stay out of the way. It’s a little cryptic at first but don’t let that scare you away. All the buttons have mouse-over tool tips… if they don’t show, try clicking the green timer area to make it the foreground program. Explore what it does a little at a time. I just realized this might be able to record audio only, and can be told to start and stop at a set time or length. More to try!
