I tried to run a program in my eclipse and I got this message
"Error: Could not find or load main class"
what can I do to fix it?

You should provide more details about what you've tried, specifically. And the obvious question is, are you certain your class has a proper main() method?

I have also received this error for two weeks, since upgrading Java. I deleted Eclipse. Downloaded newest viral protection, scanned entire computer. Rebooted. Downloaded newest version of Eclipse Neon. Corrected all classpaths. Same error. Every time.

The programs worked previously. I right click on main and run as Java application, even. Same error. Every time.

Frustrating. Environment is useless; I can't run anything.

As I said 2 years ago (above), details are important. Start with showing your eclipse.ini (specifically, are you specifying the -vm parameter) and your project's class that you're trying to run.
Have you tried creating a tiny "Hello, world" program in a new project to see if that works?
The more effort you put into describing a problem, the more effort people here will give to try to help.
