I have a similar problem regarding flash player (newest version - 22.214.171.124) for firefox/safari on MacOS 10.6:
It downloads fine, but when I try to open it, there is an error: Image could not be opened, Image data is damaged.
I have downloaded it several times from the adobe downloads page, I have uninstalled the old version, I have deactivated popupblocker and sophos antivir-software and so on. I even tried to test / repair the image with the disk-utility-program of MacOS. The test said everything ok, but repairing it was not possible (not able to open again). curious file.
I have the same problem with an other program that I downloaded recently, but old dmgs that I downloaded earlier are no problem.. Perhaps it's also a problem with my computer, but at first glance it seems to be a problem with the file. Perhaps could you also tell me the exact size the file should have? Or should I try an other, older version?
Have you tried downloading from the link in Pat's post? The DMG I downloaded is 14,779,119 bytes in size.
since I downloaded it from this site (and from the repaired link) i had no more problems. Great! I still don't understand the problem I had before but I'm glad it's fixed (:
Thanks a lot for your help!!
