These type of errors are mainly due to, improper connection between esp 12e board and your pc....Here are the things you can try:-1) Try plugging your board into different ports2) In your Arduino IDE, go to Tools => Port => Port " " NodeMcu Esp8266 12 eCheck if you can see your board in the Port Tab, with port number more than 2Generally For esp8266 12e the Port Number will be 12 or 16but it could differ3) try opening the Serial Monitor, if it opens up, then your connection is fine, and you are good to go...If your Board doesn't show up, here "Tools => Port =>"then you should refer to Step 1 and Step 5 of my instructablethis should solve your problem....if it still doesn't work, then reply back...and i will try to give some other solution

Thanks... :)

Always choose the latest one, except if you are not using any older version of Arduino IDE....but happy that u worked it out.....congo :)

I will try .... But i can't give you a timeline... May be by next weekend... :)
