Summary: Export from within Premiere Pro CS5 ver 5.0.2 produces the dialog "Media Encoder update is available", even though the updater has already been run without error and reports "no updates available". Media Encoder version is 5.0.1. The export itself runs OK after dismissing the dialog.
Details: I updated Premiere Pro CS5 Production Premium from 5.0.1 to 5.0.2, using Adobe Updater. Running updater again (from either Premiere Pro or Media Encoder) produces a dialog:
Adobe Applications Manager: "Your applications are all up-to-date."
However each time I try to export a video (AVCHD 1080i/30 from Canon HF100), Premiere Pro gives this dialog:
Dialog: Adobe Premiere Pro
"An Adobe Media Encoder update is available for this version of Pemiere Pro. To download the latest update, please run the Adobe Updater from the Help menu or visit http://www.adobe.com/go/updates"
