Adobe apps do not do well with migration. Try looking for prodesigntools for downloads of CS5.5. Follow the directions explicitly.
Because the Migration didn't do well (as Larry said, it's definitely not recommended), you might need to use the Adobe Cleaner tool to remove all traces of the migration before installing as Larry suggests.
I was able to download the InDesign installer from prodesigntools. But it won't recognize my serial number (which I'm getting from my account on Adobe's site).
I thought it be because my serial number is for the Design Standard Suite. So I went back to prodesigntools to download that installer, but am now getting "Access denied". I've tried in multiple browsers, cleared my cache and cookies, and in Chrome's incognito mode. I followed the directions explicity again but can't get to the CS5.5 Design Standard installer.
