Have since found out how to get Application Manager to allow a new download: Rename (or even completely remove!) —>Library—>Application Support—>Adobe—>caps—>Media_db.db and pdb.db. I also removed the entire —>Library—>Application Support—>Adobe—>Acrobat X Professional CCM folder and all contents, a couple of times, but this doesn't seem to be necessary or make a difference one way or the other.

BUT, despite doing three more fresh download/installs of Acrobat X Pro (via Application Manager), the same thing happens every time. "Errors on install," and neither Acrobat nor Distiller will launch. The file that is being downloaded must be corrupted on the server, not during download.

Saw a suggestion to download the "Try" version as a workaround. This may be fine for Windows users, but there seems to be no "Try" version for Mac. What's up with that???

Any other suggestions from anyone?

Hi -

Thanks for the reply. Unfortunately, this didn't work. The uninstaller returned an "Uninstall Failed" message. The message contained a suggestion to download and use the Cleaner Tool, so I tried this as well. Oddly, the Cleaner Tool could find NO CS6 applications on this machine! (Even though all of the Creative Cloud applications except Acrobat X Pro were installed successfully and are working!)

A further development: I am now also installing CS6 (via Creative Cloud Applications Manager) onto my MacBook Pro. Acrobat X Pro is, of course, the first application to install, and it installed on that machine perfectly on the first try! FWIW, the MacBook Pro is running OS X 10.6.8, while this machine (27" iMac 3.1GHz i5) is running OS X 10.7.4. Is there an issue with 10.7.4?

Hi Victoria, et al -

Update: Thinking that perhaps the Uninstaller didn't work because I had already removed the Media_db.db and pdb.db files, and the Acrobat X Professional CCM folder from the Library, I tried downloading and installing Acrobat X Pro again.

It failed in the same way but, this time, when I ran the Uninstaller per your recommendation, this appeared to worked correctly. So I then tried downloading and installing Acrobat X Pro one more time. Unfortunately, it has failed once again.

Any and all other ideas about why it worked/works fine on the MacBook Pro w/ OS X 10.6.8 but will not install on the iMac w/ OS X 10.7.4 are very welcome!

Hi -

Yes, exactly the same message (see below).

I tried the download & install in safe mode; logged in as myself first, and that failed the same way. Ran the uninstaller.

Then I enabled root, logged in as root (still in safe mode), and tried again. No joy, and the same error message. Ran the uninstaller. Disabled root. Rebooted normally. I'm done with this for today.

Tomorrow I will try verify & repair permissions (as also suggested at http://forums.adobe.com/message/4407050#4407050), then try it all again...

Please feel free to send along any other suggestions you might have! ;-)

Thanks for your efforts so far!!

Sigh. Not what I was hoping to hear. But OK.

This will definitely take all night. Again.

I'll let you know, when it's done, if it worked.

I would still love to know why it won't work on a brand-new out-of-the-box 27" iMac, with nothing but OS X 10.7.4 installed ... but worked perfectly on the first try on my older 15" MacBook Pro with 10.6.8, and a ton of other installed applications (some several generations old) to cause potential conflicts.

Wish luck!

The Cleaner can find no CS6 apps on this machine. Yippee kai yay!

Yup, the originals are gone. Long gone, what with the 5 or 6 attempts (so far) at installing Acrobat X. Manually uninstalling everything CS6 now (more than 151,000 files!). Will try contacting support to discover where to find what I'm probably missing. Worst case, I will reformat the hdd and reinstall the OS. Maybe put 10.6.8 on this machine, since it, at least, seems to work with CS6 just fine.

Despite my frustration (is it obvious?), I am thankful for the feedback and suggestions from everyone. ;-)

Update, late Friday afternoon:

Everything but Acrobat X Pro is working just fine after the complete CS6 uninstall, followed by a complete re-download and re-install. So I'm at exactly the same point I was at ~4AM last Saturday morning: Acrobat X Pro will still not install on the new iMac.

Yee haw!

It has been TWO full days (and several hours) since I sent the installation log files to Adobe "Customer Service," in response to their request for me to do so. Did a "reply all" so it went to seven other people besides the person who originally contacted me to request the log files. Maybe that pissed somebody off??

No response.

So, one day ago I sent a follow-up email asking if [they] had gotten the first email, and the logs.

No reply. Not even the courtesy of a "got it; working on it" or "f*** you."

So I just checked the open case (number 0183240407) ... and the "status" says Adobe is "waiting for a response" from ME!!!

I am so incredbly impressed right now! (Not exactly.) How's that for a response?
