We need to optimize PDF documents to version 1.4 with Fast Web View during our daily work, we use "Advanced - PDF Optimizer" of Acrobat 8 Pro, but when we optimize PDF documents larger than 50 MB, we need to wait for a long time and generally the process fails with error message saying "... memory cannot be read", I think maybe the memory overflows due to the size of the document, is there any resolution for this? Your help is really appreciated!
