Sorry if this is a duplicate from other questions but I wasn't able to solve my problem referring to this article here and here.

I'm trying to configure FoxitReader 8.0 as default external viewer for TeXstudio (2.11.2) on Windows 10.

I tried Options --> Configure TeXstudio --> Commands --> External PDF Viewer --> C:\Program Files (x86)\Foxit Software\Foxit Reader\FoxitReader.exe


Options --> Configure TeXstudio --> Build --> [add user command] --> txs:///view-pdf-external

but I still get

Error: Could not start the command: C:\Program Files (x86)\Foxit Software\Foxit Reader\FoxitReader.exe

Any help would be much appreciated.

    Welcome to TeX SX! Doesn't Foxit Reader lock .pdf files, just like Acrobat Reader? It's a huge problem when you compile the same code multiple times. – Bernard Oct 7 '16 at 17:20
  • Cannot answer, but suggest: Quotes around file "path/name"? Change backslashes to forward slashes? Perhaps instead use Foxit Reader Portable, in your home directory? – user103221 Oct 7 '16 at 19:56

    I'm not recommending Foxit as it does not support SyncTeX. Instead use SumatraPDF viewer – naphaneal Oct 7 '16 at 20:08

    see if adding quotation marks to the path changes anything: "C:\Program Files (x86)\Foxit Software\Foxit Reader\FoxitReader.exe" %.pdf – naphaneal Oct 8 '16 at 11:51

    @Bernard: You are right, but this behavior can be changed by calling Foxit as FoxitReader.exe <document> /A nolock=1 – Philipp Imhof Oct 8 '16 at 12:39

Solution using @naphaneal's and @PhilippImhof's comments:


Options --> Configure TeXstudio --> Commands --> External PDF Viewer

change this

C:\Program Files (x86)\Foxit Software\Foxit Reader\FoxitReader.exe

to this

"C:\Program Files (x86)\Foxit Software\Foxit Reader\FoxitReader.exe" %.pdf

or this

"C:\Program Files (x86)\Foxit Software\Foxit Reader\FoxitReader.exe" %.pdf /A nolock=1

to avoid Foxit Reader to lock pdf files.

  • Small edit, %.pdf won't cut it. Instead use "?am.pdf" So, this works for me: "C:\Program Files (x86)\Foxit Software\Foxit Reader\FoxitReader.exe" "?am.pdf" /A nolock=1 – Martien Lubberink Mar 8 at 5:54
