I have been learning a lot about designing relatively advanced, dynamic forms in LiveCycle Designer ES (version number 8.2). This is the version that came "free" with Acrobat Pro 9. It also appears to be the last "free" version. I have been thinking about writing up some blog posts about what I have learned. However, if everyone has moved on to more recent versions of LiveCycle Designer, then I won't bother.
I still use it. While I was on vacation last week IT upgraded our MS Office from 2007 to 2010, which is not compatible with Acrobat 9, so now I have no Acrobat Ribbon in Office or Outlook (I also used to archive all my emails into PDF in Outlook). Acrobat X is compatible with Office 2010, but no LiveCycle in X. All of my forms are in LiveCycle Designer ES 8.2, so if I upgrade to Acrobat X, I lose LiveCycle. . . I'm trying to figure out if it is now a separate stand alone or if it's gone all together and they've moved forms into something else. Maybe Adobe is getting like the airlines . . .
