Could you please provide more information on exactly which part of 1 is not working? "1. 5.7 manual installation, but not working: http://www.adobe.com/support/downloads/thankyou.jsp?ftpID=4680&fileID=4364"?
1. Were you able to download the .dmg file?
2. Were you able to double-click and open the downloaded .dmg file?
referring to part 1
the link to the manual installation on the adobe website does not appear to be working :
The 'download now' button in this link:
The 'download now' button in that link above takes me to a page which says :
"The requested URL /pub/adobedobe/photoshop/cameraraw/mac/5.x/Camera_Raw_5_7.dmg was not found on this server."
It is that link to the manual installation version of 5.7 that is not working and which could not result in me downloading any dmg.
For the 2nd link i indicated in the previous post - the 5.7 installer/ updater software link :
I was able to download a dmg . However i then had the problems i indicated.
We've fixed download link on this page: http://www.adobe.com/support/downloads/thankyou.jsp?ftpID=4680&fileID=4364 so the manual install should work now.
I apologize for the broken link and thank you for reporting.
