I have a customer with a HP system running Windows 7 Home Premium with 6GB RAM and they are running Illustrator CS5; it is a standalone machine with not even a connection to the Internet or Email. They use an addon for Illustrator called Fine Cut which sends images to Raster Link5 software so their printer can print and cut out the image. They open an Illustrator document, go into Fine Cut to make cut lines around their image, then is sent thru raster link to the printer.
In Illustrator,they get an error: "Can not perform processing because of insufficent memory. Increase the memory size available for Illustrator." They have increased the virtual memory to 10000 as I have been told.
