# AUCTEX won't create dsc file

I'm using Emacs24 on windows with AUCTEX for Latex. When I try to toggle preview it doesn't show, insteed there is a little "not working" picture on each equation and I get an error

Running Preview-PDF2DSC' with pdf2dsc "region".pdf "region.prv/tmp9244b3d"/preview.dsc'' Files\gs\gs8.71\bin\gswin32.exe/==/ was unexpected at this time.

Preview-PDF2DSC exited abnormally with code 255 at Wed Sep 6 14:30:04 PDF2DSC sentinel: Opening input file: No such file or directory, c:/Users/menis/Dropbox/master/LaTex/region.prv/tmp9244b3d/preview.dsc

Note: I checked and Emacs is able to read PNG files. Also Latex-preview-pane is working properly so I guess ghostscript and doc-view are also working fine.

Any ideas what the problem is?

• Can you update your Ghostscript to 9.21 and try it again? Sep 6, 2017 at 19:19
• @ArashEsbati I updated and got the same error : TeX Output exited as expected with code 1 at Thu Sep 7 08:47:51 Running Preview-PDF2DSC' with pdf2dsc "region".pdf "region.prv/tmp9052H2N"/preview.dsc'' Files\gs\gs9.21\bin\gswin64.exe/==/ was unexpected at this time.

• I experienced the same error message, but it turned out that the LaTeX code itself had a mistake: I did a $$and forgot the$$. You should try to compile your code, and the compiler will help you find the error. Alternatively, preview over smaller and smaller regions until you isolate the typo. Dec 9, 2017 at 22:56
