I finally have my Win7 64-bit computer working properly, after a month of virtual hell. My Z3100GP PS is printing nicely. However, when I try to access the HP Printer Utility Color Center to synchronize my paper presets, nothing happens and then the printer utility goes non-responsive.
I know that HP is not planning on software/firmware updates until June, 2010 (hopefully), but the Vista 64bit stuff seems otherwise to be working OK. My thought is that the Color Center is looking for the paper profiles in a different folder than where they got installed, but I am reluctant to copy them into the folders just to try them out. As it is, I have put them into the following folders, and they work for printing from Qimage as well as for Photoshop's SoftProofing:
Are there any other places that Color Center might be looking for paper profiles?
