@Paul O'Brien: I can't do that because it's a department wide requirement/upgrade for me. If I used this as an individual office product then I would never have downloaded Adobe DC and just stuck with XI Pro.

Hello all, guess what? You can uninstall Acrobat DC and reinstall Acrobat XI, although Adobe doesn't make this very clear. Sadly, Acrobat X is not available unless you already own a license key.

Here's how (for WIndows):
1. Download the Acrobat XI Pro Installer (https://helpx.adobe.com/download-install/kb/acrobat-10-11-downloads.html)
2. Uninstall Acrobat DC via the Windows Add/Remove Programs tool.
3. Close other programs (esp. Office, et al).
4. Run the installer. It will ask you if you'd like to overwrite any existing files; do it.
5. Rejoice.

I have been using DC for over 2 months now and can only say that the new UI is a complete mess. For Example "Fit Page" is now buried in a drop down as "Zoom to page level" Tool bar Icons are way too big. Fine if you are using a large monitor but way too big for a 13" 4K Laptop, Working area is now too small. Please go back to Adobe Acrobat X design!!!

Previous versions had better tool bars. In the name of progress and innovation, the user interface has gone downhill.

This absolutely needs to happen. I don't want the share, help, and notification buttons on the right; or the Home, Tools, and Document "tabs" on the left. All these do is take screen space away from the tools for which I do want easy access. The entire contents of this toolbar should be customizable.

I use Acrobat a lot on a second screen, the toolbar/comments being on the right side of my screen makes this being on my far right eye corner.
I would love a preferences where I can move the toolbar to the left side of my window.

I agree that having to save everything before emailing is a true hassle. I don't always want to save the document. now I have a random junk file I have to save things to and delete once a week. Terrible idea on adobe's part.
also even after installing the patch, I have an additional drop down to zoom in and out rather than the convenient +/- that used to be at the top. I can zoom back to single page view now by adding it to the tool bar. I'm just not sure why it adds that button to the page up/down tool bar rather than the zoom tool bar. Either way its there and easier to use once added.

Since the update, I hate that now there is a dropbox that must be selected to change to fit to one page. Also, the option to email a PDF directly is now a nuisance because you must save it first. Change these options back to how they were before! And why the blank area in the tool bar now? Waste of space!

Clearly, it's not obvious to most that almost any button except "Share" can be removed from the tool bar. It's not the fault of the users that people can't figure that out, it's the fault of the the software UI designers. Make it clearer that simply re-selecting a button from the View>Show/Hide menu will show or hide a button. It took a while to figure that one out.
As for the ridiculous giant "Share" button, what were you thinking? That's TERRIBLE.

Agree with everything here. Ever since this update was pushed to my computer by our IT group, I've hated it. Such a horrible UI. Let us customize our toolbars with what we actually want. When I snap the window to once side, I'm stuck looking at the stupid share/feedback/help/notification buttons that I have zero use for. Let me see what I actually want Adobe!

Some icons in the toolbar are useless to me e.g. Share, Home, Tools...it would be nice to be able to customise them.

NEED for more flexibility with toolbars. Urgent need to remove some items from individual toolbars OR to add some options without having to add the others.

For example - the ability to set the "zoom" to "zoom to page level" showing rather than the default "show page to actual size" (which ends up with a ridiculous mega-sized page that takes up the whole damned screen (making it virtually impossible to work with other applications open as well).....

I agree in the comments. All the unnecessary buttons in the top bar is a nightmare! I am angry.

I thought I was the only one who was upset about DC not allowing the user to remove certain icons that serve no purpose. We pay a lot of money to have this program on our computers so it would seem that you would listen to us when we ask you to change certain features. Especially when it's a vast majority of people complaining about the quick toolbar setup.

I find it disheartening that Adobe seems to be ignoring the feature request with the HIGHEST NUMBER OF VOTES!

I would pay good money to revert back to XI at this point. After hundreds of posts complaining about DC all I can figure is no one at Adobe really gives a ****. Otherwise they would be doing something to preserve their customer base by now. Right Adobe?
What a joke. Just another case of a big bloated company that doesn't listen to its customers. Maybe once people stop paying their renewal fees they will wake up. Hope it's not too late by then.
DC, just like Windows Vista a bad idea.

I also believe that DC is a UI disaster, so I’ve tried most of the Acrobat Pro alternatives mentioned in this forum in the hope of upgrading from XI. Unfortunately, there are a number of proprietary Acrobat features that none of them seem to support, forcing me to stick with XI for now. For instance, none of them support initial view preferences like the “Two-Up (Cover Page)” layout and “Fit Page” magnification. I also like to option-double-click on a graphic to open it in Photoshop or Illustrator, and to view comments as a list on the right side of the window. Acrobat DC has been in the wild since April 2015 and it hasn’t been improved one bit. So Adobe, please tell us your future plans for Acrobat so we can strategize accordingly.

Hey Adobe, 89 comments and counting. Are you ever going to chime in and let us know where you are with this? I mean, come on! This request has been under review for over a year!

As the requester of this initial comment, not only has there been no feedback, but am now dismayed to see the Menu bars have been made worse still by the addition of 'SHARE' - Because EVERYONE wants to share PDFs using Adobes system - so much so that you need a BLUE button on a GREY menu - & made sure that it HAS TO BE SEEN even when the application isn't maximised - on a Half-snapped screen the only useful buttons left are now 'Save' & the Page number - I suspect they only survive because I turned off the existing 'Cloud, Send buttons)
No Fix, No Options, introduce another problem....great way to retain subscribers.
