First, I use TeXstudio and I have MikTeX 2.9.
I tried to make TeXstudio automatically install it but it gives me an error saying it cannot find polynom.sty. At this point I go around the internet trying to find a solution and I find it. In a few words, I have to install the package manually by first downloading the files from CTAN, which I did, and then open the two files .dtx and .ins with my editor and compile them, which I did but that gives me this error:
Could not start Default Compiler:PdfLaTeX:
pdflatex.exe -synctex=1 -interaction=nonstopmode "polynom".tex.
I also ended up with a texput.txt saying this:
This is pdfTeX, Version 3.14159265-2.6-1.40.16 (MiKTeX 2.9) (preloaded format=pdflatex 2016.4.15) 28 MAR 2017 15:30

Here is how much of TeX's memory you used:
2 strings out of 493634
17 string characters out of 3141299
52604 words of memory out of 3000000
3491 multiletter control sequences out of 15000+200000
3640 words of font info for 14 fonts, out of 3000000 for 9000
1025 hyphenation exceptions out of 8191
0i,0n,0p,1b,6s stack positions out of 5000i,500n,10000p,200000b,50000s
! ==> Fatal error occurred, no output PDF file produced!
I don't really understand what's the problem. Can someone help me?
