[Tex/LaTex] Could not start Default Compiler: PdfLaTeX

editorsmiktextexstudio

I've been using TeXstudio without any problems for a while.
Now, whenever I try to compile some documents I get this error:

"Could not start Default Compiler:PdfLaTeX:
pdflatex.exe -synctex=1 -interaction=nonstopmeode "Name_Document".tex

And the message I get is:

"Sorry, but pdflatex.exe did not succeed. You may want to visit the MiKTeX project page, if you need help.
Process exited with error(s)"

Also, if I click on Help–>Check LaTeX Installation I get:

"Could not start :: pdflatex -version"

I've also tried to download again the last version of TeXStudio, but nothing changed. My test code is:

\documentclass[12pt, a4paper]{article} 
\usepackage[italian]{babel} 
\usepackage[latin1]{inputenc} 
\usepackage{amsmath} 
\title{\textbf{Titolo}} 
\author{Autori} 
\date{\today} 

\begin{document} 
\maketitle 
\clearpage 
Questo è il mio primo documento in \LaTeX. 
\end{document}

After installing portable MiKTeX I had the same problem running texify with a parameter –-interaction=… I have disabled lines

// IfStr("%$('%!9-No_Interaction');","1",!"=",>
//  !|LetReg(4,'%$("TeX-Opt");--interaction=nonstopmode');|,>
//  !|LetReg(4,'%$("TeX-Opt");--interaction=errorstopmode');|);  

in PDFTeXify.edt and have no problems.
