IBR 11g does not support 64-bit Ghostscript
By Kevin Smith-Oracle on Mar 30, 2011
I recently installed IBR 11g on Windows Server 2008 running on a 64-bit machine. When downloading Ghostscript there was a 64-bit version available so I thought I would use that.
gs901w32.exe, GPL Ghostscript 9.01 for 32-bit Windows (the common variety).
gs901w64.exe, GPL Ghostscript 9.01 for 64-bit Windows (x86_64).
When I tried to configure the Distiller engine in IBR I received this message:
Unable to load configuration options. The path to Ghostscript is not valid.
File 'E:/gs/gs9.01//bin/gsdll32.dll' does not exist.
It looks like IBR is hard coded to reference the 32-bit dll. I had to uninstall the 64-bit version of Ghostscript and install the 32-bit version. Then I was able to configure the distiller engine successfully.
I guess my first clue that the 64-bit version of Ghostscript was not going to work should have been the Win32 Ghostscript Settings heading on the Distiller Engine Options page.
Hopefully they will support 64-bit Ghostscript in a future release or patch.
