Is there a 64bit version of Acrobat Pro DC 2015 available? If not 2015 then is there any other version of Acrobat DC Pro available in 64bit?
Yes, Adobe Acrobat for Mac.
Nearly all current Adobe products are 64-bit apps. If you are not using the latest update, you could receive an error.
We have also released an update today for Acrobat/Reader which is compatible with the lastest Mac OS Catalina. In the application, go to Help > Check for updates. To check the latest version, refer to this link https://helpx.adobe.com/acrobat/release-note/release-notes-acrobat-reader.html

Hi Bernd. Thanks for your response. I am actually looking for Windows OS (Windows 10 or 2016) and have not found any 64bit Acrobat Pro DC version yet.
There is none. May I ask why you feel you need it? (The 32 bit version is fully compatible with 64 bit Windows, and a 64 bit version wouldn't perform better; it could use more than 2 GB of memory, but I've never seen it need to).
Hi Bernd. So the problem I am running into is that I have Office 365 64bit in my Citrix environment (still in Dev Phase though) and I have Adobe Acrobat DC Pro 2015 32bit installed on the same image. When I launch Outlook it just freezes and after spending lot of time I found out that if I disable the "Acrobat PDFMaker Office COM Addin" (in Outlook) and re-launch Outlook it starts working fine. The Add-in DLL version is 15.6.30475.53472 (C:\Program Files (x86)\Adobe\Acrobat 2015\PDFMaker\Mail\Outlook\PDFMOutlookAddin.dll). So I was just curious if I should try 64bit Acrobat and see if that fixes the problem. thanks
There is no 64-bit version of Adobe Acrobat for Windows at this point. That having been said, we know of no incompatibility between Windows 64-bit, Office 64-bit, and Acrobat. In fact that is the environment in which I personally run, although my situation is not complicated by the Citrix environment.
There will likely be a 64-bit version of Acrobat for Windows in the future, but nothing has been announced yet. And when it is made available, don't expect that 64-bit will be retrofitted to Acrobat 2015 or 2017, but rather for the Acrobat DC versions.
I have Acrobat Pro DC and I am constantly getting drawing errors, after which I have to restart. The probable cause is running out of memory, as I tend to leave Pro DC running for a day or more at a time because I use it so much. A few updates ago, I didn't have to restart so much, but now that I have many documents in my history list, and no way to get rid of them, this is happening so much that I have to exit it after every document.
I really don't need 1000+ documents in my history view. I think Adobe should give me a way to remove them, fix the drawing error problem or assign an engineer to port the 32-bit version to 64-bit, which would allow me to take advantage of my 32-gig memory. As it is, I am confined to less than 2GB.
FWIW, it is highly unlikely that “drawing errors” occur due to running out of address space. You would get “out of memory” errors instead.
That having been said, read my response marked as the “correct answer” in the thread at https://community.adobe.com/t5/acrobat/adobe-acrobat-pro-32bit/m-p/11831560. If you are willing to be on the bleeding edge, there is now a 64-bit version of Acrobat Pro DC (and Acrobat Standard DC) for certain localities.
If there's anything that 60+ years as a software engineer has taught me, it's that running out of memory rarely evokes "out of memory" errors. 😉 Bitrot strikes in unexpected ways.
That said, thank you so much for responding; I hadn't really expected a reply after the thread had been idle so long. I am delighted to participate, and am downloading the 64-bit pro installer as we speak.
Thank you again, Dov.
Bummer. The 64-bit installer tells me I already have a "more functional product" installed, i.e., 32-bit Pro DC. Which means in order to install it I'd need to uninstall the 32-bit version. Is there a way around this? I'd much rather keep it as backup.
