Adobe Acrobat After installing - Unidentified Developer Error Message

[tonydi31]

I downloaded Adobe Acrobat Pro from your Adobe site. I went to install it and after the verification process, I am getting this message:

Error Message -  Acrobat pro.app can't be opened because it is from an unidentified developer? I downloaded Acrobat Pro from your site and after installing it will not open? Why am getting unidentified developer when it was downloaded from your site?

Why the error.

The message is a little suspicious. Please give the exact URL you downloaded from. Don’t run it yet.

This is the URL for the download I received. If this is not correct URL, can you send me the correct URL to download most recent updated Acrobat 9 Professional?

Download Acrobat 8 and Acrobat 9

Thanks,

Tony

Oh, Ok. That software is too old to be digitally signed, hence the message. Won't run on new Mac either.

MVP Thanks,

I presently have Adobe Acrobat 9 Pro (a 32-bit version) for Creative Suite 5 that will not work on my iMac Sierra V 10.13.6 because It is a 32-bit version. Is there a link to download an upgraded 64-bit version of Adobe Acrobat for Creative Suite 5? The creative suite 5 came with some apps with the ability to run 64bit versions like Photoshop, Illustrator etc but not Acrobat 9 Pro?

I was able to run the 32-bit version of Acrobat 9 pro up until my last update of Sierra. Is there a link to download a current upgraded 64-bit version of Adobe Acrobat 9 Pro for creative suite 5?

Thanks, Tony

No, Acrobat 9 never had a 64-bit version, is over four versions out of date, and is no longer supported by Adobe. You would need to subscribe to Acrobat Pro DC or license Acrobat Pro 2017 to get 64-bit support.
