I open TeXstudio, I press
File->New from template-> Article->Ok then I use the double green arrow to compile (the play button didn't work either) and view the pdf. After that I want to save that pdf so I use
File-> Save As... and then I save it as a pdf file but I can't open it using Adobe reader or even Sumatra Pdf reader.
If someone can tell me step-by-step the instructions that I have to follow I would appreciate it.
EDIT: I got it to work. In TeXstudio when saving I used
Save As->All files then I clicked the
Build&View button and then the play button.
