Hi! I have downloaded latex from this web site but I have som problems. When I am done with my work I have written in Latex I can not open it to see how it looks. I am a Windows 8 user. I hope that you will help me to solve my problem.
First of all. TeXstudio is a LaTeX Editor. You need a TeX distribution, such as MiKTeX  or TeXlive  to create a document
So, my guess is, that you didn't install a LaTeX program.
