This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • Please tell us more about how you installed MikTeX. Please also show us lines 1 and 2 of the tex file. (By the way, beamer.cls is not a "package" -- at least not in the LaTeX sense of the word. It's a so-called document class file.) – Mico Oct 18 '17 at 5:16
  • It was just few steps that I followed , nothing was odd! BTW I didn't install it in my program files ! does it make problem ? – Red shoes Oct 18 '17 at 5:20
  • afaik beamer should be part of any standard latex installation, thus I guess your editor doesn't recognize your local tex distribution. go to 'options > configure > commands'. Are all or most of the fields blank? – thymaro Oct 18 '17 at 5:21
  • @Mico I updated the picture. thymaro : No they have been filled out, but I installed Takmaker before MikTex ! Does is make problem ? – Red shoes Oct 18 '17 at 5:28
