hello house, please i just installed Proteus 7.9 on my system, But when I tried to run the software, it show that the licence key is bad, How can u rectify this, or better still help me with any link that I can get the latest and best circuit simulating software, I have tried various site when I Google But didn't get any, even the one I managed to get is not working. please help.

 

You're asking us to help you run pirated software?

I suggest instead you investigate LTspice, the free simulator. Widely used around here. A little hard to get started but it works well once you learn the interface.

 

Thanks for the reply, will head to my search engine

 

never knew it was pirated

 

I just finish installing ltspice 4, like u said, it's really hard, can't seems to find any components at all...a little guide will be appreciated..

 

Read the docs. It's all in there. You'll want to learn the keyboard shortcuts to pull up components, the move, delete, drag tools and so on. The most common tasks all have a shortcut.

Once you get a drawing done, and be sure to start as simply as possible, you'll want to learn how to run the simulation and plot results. Using example files is a great way to see how that's done.

 

Thanks So much.
