Hi everyone, again,
Really sorry for posting twice. I have messed up some issues in the previous post.
I am currently using TeXstudio2.5.2(SVN 3661) on Windows7 64bit.  And I want to include an eps formatted image to create a pdf file. But I failed.
In TeXstudio, I changed the default settings to:
Latex -> "C:/Program Files/MiKTeX 2.9/miktex/bin/x64/latex.exe" -src -interaction=nonstopmode %.tex
Dvipdf -> "C:/Program Files/MiKTeX 2.9/miktex/bin/x64/dvipdfm.exe" %.dvi
Ghostscript -> "C:/Program Files/MiKTeX 2.9/miktex/bin/x64/dvipdfm.exe" "?am.ps" 
When I use 'DVI Chain' as the 'Build & View' option, the dvi file just looked fine.
But when I tried to convert DVI file with dvipdfm.exe in command window, or use 'DVI->PDF Chain' in TeXstudio, the following messages just came up and then the operation was faild.
=========== message of TeXstudio ============

(I inserted some blank lines to make it more clear to read.)


I searched the web to find a solution. Someone said that it seems to be the problem with mgs.exe on Windows. But I still cannot figure out how to solve this problem.


I use Latex both on Linux and Windows, and synchronize my work over the two platforms. On linux I just use eps files, so it is best to use eps files on windows, too. And pdfLatex is just not my option.


Again, any help is appreciated!


Thanks !!!
