I have a very similar question, maybe partial answer for Myrtle?
I've recently switched from XP Home 32-bit, to Windows 7, 64-Bit, Home Premium, and it only installed a BASIC version of my 1310 Series All in One, no Scanner and No "Print Selection" for if you only want a hilighted paragraph of a long article.
Discovered Solution Center FRAMEWORK in Programs and Features, to be changed or uninstalled. I don't think it's in Libraries. Is this what we're looking for, and how to activate it?
Would it be safe for me to try that gc_wOL_ENU_NB psc 1310 Series All in One
which was actually for XP 32-bit? I guess that was Full Feature, and I also have my original 2007 Disk, but afraid either of these solutions might erase everything and I might not be able to reinstall.
