I've tried downloading HyperCam 2 tons of times, but after the download there's nothing to be found. I can't find it in the search on the start menu and if I click the option that opens it right after the download (Which is the only way it works), pin it to the taskbar (I have Windows 7), and try to re-open it I get an error message saying it's been moved or deleted. Is there any way to fix this or is there any good alternatives? (Besides Camstudio, because I get tons of error messages sometimes and the computer can't read the video files.)

Click here and see if it does anything, then try to run the setup. You may want to go into control panel and uninstall anything Hypercam 2 related first.
If that doesn't work, try out this list: http://www.hyperionics.com/hc/downloads.asp
