ATmega328 5V 16MHz instalation problem

Hello, I want to connect this clone of Arduino Pro Mini to PC. I plugged it correctly and set it up in IDE too.
Here photo of it and screen of error message. I got a RS232 converter to connect. Please help.


When you post images to the forum You should attach and embed the image following these instructions:
(Out of Date) Guide: How to Insert Uploaded Images in a Post - Website and Forum - Arduino Forum. This will make it easier for people to see and will make it more likely for you to get help.

That converter cable doesn't have a DTR or CTS line so it won't do auto-reset. This means you will need to press the reset button on the Pro Mini at the right time every time you want to upload to it. I recommend buying one of the breakout boards that plug right in to the Pro Mini and will do the auto reset so you don't need to do it manually.

So, when i upload in IDE i just must push the reset button ? thats all ?

If you have the cable connected correctly then resetting the Arduino just as the upload (not compilation!) begins should fix your problem.

I try it, but it didn't help.
