with CS5.5, Win7/64, I have the same & well known problem that I can't save PDF presets within InDesign, e.g. s. http://forums.adobe.com/thread/565361
However I am working with an administrator account and I can save presets within Word 2010 which thereupon are selectable in InDesign -- but not vice versa.
But now I want to reinstall Win7/64 on a SSD together with CS6.
Still exists this problem in CS6? Or are there any requirements which I have to attend?
