After installing Adobe Air Runtime (http://get.adobe.com/air/?promoid=BUIGQ) I do not have the Acrobat_com.exe file in "C:\Program Files\Adobe\Acrobat_com\Acrobat_com.exe". On the other computers this is the file that I am using to start Adobe Air. I have removed the application and reinstalled several times along with a reboot. On other Vista and XP installs this has not been an issue. Any ideas?
