I am going to jump back in here again. I, too, just migrated from WIN XP to WIN 7 64-Bit and from MS Office 2007 to MS office 2010. I do NOT use the "Save As" function for .pdf's because of poor quality (specifically, when color graphics are involved). I ALWAYS print to ADOBE PDF (from the printer drop down menu)...which is nothing more than a pdf converter and have always had good quality IMO. I don't know much about Adobe Creative Suite but, if it is similar to most Adobe products, it should have ADOBE PDF in the printer drop down menu. If so, try it. If not...I am at a loss.

I forgot to mention that when you use the print to ADOBE PDF method, a menu will be generated for you to save the .pdf to your file location (it doesn't actually print to anything).

Thanks. That doesn't work on my system currently. The PDF printer just seems to ignore the print commands from Office 2010 software. I noticed that your new system is running Adobe Acrobat Reader X, and not the Creative Suite you used to have. Based on your input, I have a theory that if I uninstall the current PDF printer and try to re-install it through Acrobat X, it might help. I haven't had a chance to test that theory yet.
