# Configure TexStudio for first use

I am trying to configure TexStudio for first use. If it makes any difference I downloaded Protex onto a machine running Windows-XP.

Under Options Configure TexStudio on the left I click Commands when I have the following: DVI Viewer - the path includes a folder that does not exist, but it points to a file I do have (yap.exe) so I am assuming I can just change the path so that it leads to where the file actually is. Alternatively, does it make more sense to change my directory tree so that the file is where the path says it should be?

PS Viewer - the path includes a folder that doesn't exist, and leads to a file I do not have (gsview32.exe).

Ghostscript - the path includes a folder that doesn't exist leading to a file I do not have (gswin32.exe)

Additionally, in MiKTex Maintenance Settings on the Roots tab, I notice there is nothing under Path which suggests to me that even if I got TexStudio working MikTex would not know where the files are.

Is anyone able to advise how I should proceed from here?

Welcome to TeX.SX! (I presume; I'm on mobile.) All of those indicate use of vanilla `latex`, TeXStudio has an option to use `pdflatex` instead which, unsurprisingly, produces a PDF by default. Using this executable is generally easier (unless you are using a package that ties you to PostScript, like `pstricks`). (Note the format is exactly the same—it's all still LaTeX.) –  Sean Allred Oct 20 '13 at 3:57
A good way to test if MiKTeX is installed is to run `tex --version` from the command line. –  Sean Allred Oct 20 '13 at 3:58

1. It's perfectly fine to change the path in the TeXstudio options. That's what they are for.

2. GhostView / GhostScript are two external programs for viewing and converting PostScript. You only need them if you use a `TeX -> PS` or `TeX -> PS -> PDF` workflow (i.e. using `latex`). This is rarely used nowadays and you would know if you have that special requirement. If you don't know about this and only want to create PDF as output `pdflatex` is most certainly the way to go. Then you can ignore GhostView and GhostScript.

3. By default, MikTeX doesn't put it's bin folder on the PATH. This means you have to specify the full path to the commands in Òptions -> Commands`. Alternatively, you may put the bin folder on the PATH yourself. Then the command name is sufficient. Note: This is also handy when you want to run some tools from the command line.

4. You can test, if TXS finds `pdflatex` by going to `Options -> Check LaTeX Installation`. At the top of the System Report there should be something like this:

``````where pdflatex: C:\Program Files (x86)\MiKTeX 2.9\miktex\bin\pdflatex.exe

PDFLATEX: pdflatex -version
MiKTeX-pdfTeX 2.9.4487 (1.40.12) (MiKTeX 2.9)

5. MikTeX Settings -> Roots tab: It is empty by default if the checkbox "Show MiKTeX-maintained root directories" is not checked.

To Add Point 4: To Test for `pdf compilation` on TeXLive/MiKTeX(hopefully) distro use `pdflatex sample2e` and `xetex opentype-info` at Comman line/Terminal (Wonder if it can included in TeXstudio) –  texenthusiast Oct 20 '13 at 16:45
In MikTex Settings I clicked on Refresh FNDB and it just seemed to start working after that even though the paths in TexStudio have not changed at all. Either way, I'm up and running and you can close this question as answered. Thank you @Tim Hoffman –  Martin Oct 20 '13 at 16:51
