ERROR: Cannot open PDF
If a PDF does not open in EMu and instead you recieve an error message that states something similar to:
"Postscript delegate failed "C:\Users.... No such file or directory @ error/pdf.c/ReadPDFImage/"
Then you will need to update the computer's version of Ghostscript.

Using the link provided, download the GNU Affero General Public License of Ghostscript 9.18 for Windows (32 bit). Even if your computer runs on a 64-bit Operating System, EMu requires the 32-bit version.
Restart EMu
You may need to restart your instance of EMu in order for the update to take effect.
In the event that restarting EMu does not work, restart your computer.
If after restarting your computer you still cannot open a PDF in EMu, please contact an Information Manager.
