# Other problems

See the File associations page about trying to configure which program should open which type of file.

Other limitations of a RES UWP:

• Many applications are virtualized. This complicates integration into TeX Live. This is e.g. the case with WinEdt, which is available to some users. See the WinEdt page.
• Settings are preserved between logins only if that has been explicitly configured by ICT staff.

Some specific problems you may encounter when running our TeX Live:

## How can I configure TeXnicCenter with Adobe Reader as pdf viewer?

This option is no longer supported. The TeX Live Launcher has an item under Tools to reconfigure the TeXnicCenter output profiles. There used to be a choice between SumatraPDF (a component of our TeX Live) and Adobe Reader. When in the past RES made this more difficult, I dropped Adobe Reader altogether, also because of the advantages of SumatraPDF (no file locking and source-pdf synchronization). Of course, you can still view the generated pdf with Adobe via other means.

## The LaTeX editor cannot view the pdf

If there is a built-in viewer (TeXworks, TeXstudio), use it. Otherwise, try SumatrPDF. The location of our SumatraPDF is `\\workspace.rug.nl\aps\serverbased\texlive\2016\rugextras\sumatrapdf\sumatrapdf.exe`

Or try to double-click the pdf in Windows Explorer or in another file manager.

## The LaTeX editor no longer generates pdf

This may be due to damage to your profile, to changes in the underlying system, or Adobe Reader or Acrobat may have locked the file. If file locking is not the problem, try to refresh your settings: close your LaTeX editor, run the launcher from the RUG menu and click on Tools / Re-initialize TeX Live.

## LuaTeX or XeTeX hangs

Probably LuaTeX or XeTeX is just busy generating or updating a font cache. This can take a long time. In the case of XeTeX it may be necessary to update the font cache separately. The Tools menu has an entry for this.

## TeXnicCenter- or dviout help does not work

These programs use compiled html for help. Windows considers this file format – like many Microsoft-developed formats – too unsafe to handle unless the file comes from a safe location. At the same time, Windows may not recognize our network drives as safe.

Workarounds: I know of no workaround which works from within TeXnicCenter or Dviout. But some relief can be had in one of two ways:

• Copy the helpfiles concerned to a local drive. You can get at them via the launcher: click File > Browse the TeX Live installation. The TeXnicCenter help files are in the 2016 \ rugextras \ TeXnicCenter \ Help subdirectory, the dviout help file is 2016 \ tlpkg \ dviout \ dvioute.chm. Or:
• Install the ChmFox Firefox add-on into Firefox and restart Firefox. Now you can view the chm help files with Firefox. Because the files may be a bit hard to find, you can copy-and-paste the following strings to Firefox and then visit and bookmark them (they do not seem to work as hyperlinks):
• chm://///workspace.rug.nl/aps/serverbased/texlive/2016/rugextras/texniccenter/help/texniccenter.chm!/root.html
• chm://///workspace.rug.nl/aps/serverbased/texlive/2016/tlpkg/dviout/dvioute.chm!/CONTENTS.html (last time I tested, I failed to open dviout help in this way)
