OMG, OMG! I recovered it, it's back!
I keep most of my downloaded install files, which included AdbeRdr11010_en_US.exe . After de-installing Adobe from my (Win 7) system I ran that older file. It expanded into Reader 11.0.10.
I tested it with my 2,124-page Principles of Operation pdf. There it was, my familiar GUI with comments on right and bookmarks on left! Oh, I am so relieved. Work has been very difficult up to now.
PLUS, there is an option at the end of the install to restrict updating. You can guess how I set that! My very best wishes that you all may find this version. I just gave myself a great holiday present.

I was a daily and intensive user of Adobe Acrobat, and I have become so disoriented and frustrated with this new version.

I want a way to hide the toolbar or move it (preferably dock it like before), as it currently slows down some of my work as it is placed now.

the new e-signiture gui and send changes are not effective. for example, when you already have places signitures panels in the document, these are ignored in the update and new e-signatures panels have to be added. This is frustrating as they also need to be resized accordingly. Our issue is compounded as we have documents with multiple panels for signiture, now I have to place each one. The new process requires extra effort, so it's not an "upgrade" on the previous. It also makes little sense to split the process to add persons to the document. Instead of doing it all in one go, its now split into two stages for signitures and copying people in - terrible choices all round; but I suppose it is consistent with the other terrible changes you have been making recently. I'd use a different product if there was an alternative - you've opened the door to potential churn of customers.

I want to be able to USE this, not try to figure out where you hid everything. This is like Microsoft constantly shifting the menus and then finally hiding everything behind the stupid ribbons. I don't want to have to re-learn something for a UTILITY, especially when it offers NOTHING!!!

I typically refrain from providing feedback on products, but I felt compelled to express my thoughts regarding the recent layout changes in Adobe Acrobat. Despite recognizing the effort put into these updates, I must admit that the new layout is not meeting my needs. Just today, I found myself unable to work efficiently on a PDF, leading me to switch to PDF Expert out of frustration. It's notable that I subscribe to Acrobat for myself and several other users (under a different email account, not the Gmail one I'm currently using, though I am willing to share those details with an Adobe representative if needed).

The crux of my issue lies in the user interface; I'm spending an inordinate amount of time locating features that were previously intuitive. This constant search is not only inefficient but also quite aggravating. It's a classic example of the saying, "If it ain't broken, don't fix it." This principle, often cited in engineering, seems pertinent here. I believe it's crucial to have the option to revert to or choose a different layout that aligns more closely with the user's preferences and workflow efficiency.

Hello?! Is ANYONE at Adobe monitoring this? How about a response please?!

Dear Adobe, I have been using the new updated Adobe since its release until December 15, 2023. I am an attorney and use Adobe Pro very often. The new update should not have been released. There are numerous bugs. For example, the signature function hardly works because the signature freezes all the time while on the page. Very difficult to get it where it belongs. The program also crashed more regularly. Next, the add text to a PDF no longer allows a user to add the text where they would like. Now, you have to just edit already existent text which is very far from idea. Also why are the page numbers on the side of the viewer?
I commonly have multiple documents up on my screen and now if there is any overlap (there commonly is), I cant see the darn page numbers. There are other annoyances and bugs besides these. Think this new version is not ready for prime time.

This is the reason nobody gives a ****. They are living for quarterly stock profit reports. Does anybody see any humans in the ownership tree? I don't. Dump the product and show a huge quarterly loss for Adobe. Then maybe the investors will sell out. Either that or kick the CEO's *** and make him fix it. Maybe somebody useful will buy it. Who knows! Sadly, I am 64 years old, and in all my years I have never seen anybody do the right thing in this situation. I have no idea why. Entrenched processes and ideas are difficult to change. People cling to them. You have to literally pull things out of their hands and physically take them! They need to hire me. I'll fix it for them. I have had to do this before. This is absolutely ridiculous!

Who owns majority of Adobe? This is absolutely crazy! No humans!!!!!
Largest shareholders include Vanguard Group Inc, BlackRock Inc., State Street Corp, VTSMX - Vanguard Total Stock Market Index Fund Investor Shares, VFINX - Vanguard 500 Index Fund Investor Shares, Morgan Stanley, Fmr Llc, Geode Capital Management, Llc, Jpmorgan Chase & Co, and Invesco Qqq Trust, Series 1 .

Yay!

Anyone who doesn’t know to turn off auto updates after disabling the new version: it’s an option under preferences. Personally, I think Adobe should have had someone in authority come out and actually say SORRY for how much anxiety and issues they caused their core audience with the original enforced and unannounced launch of that new abomination. Sadly the days of this company having anything but reps that resemble engineers portraying chatbots is long gone

If you search a little, you can even find an older version of Adobe Acrobat Professional that Adobe themselves officially have made available for download free of charge.

This is a beautifully stable version with normal menus, low memory requirements and high performance, coded by great people who have long since left Adobe and been replaced by jerks from kindergarten.

It's absolute junk. It's buggy, it's slow, it's much more difficult to do simple tasks, and even after four months of familiarizing myself to the new layout, I'm still a lot less efficient because it's so counterintuitive. It's complete garbage. I just learned of reverting to the old interface, but I've seen that people are having troubles with crashing, so that's not good either. Come on, Adobe. Do better.

You had better have a pretty good reason, and some pretty advanced cyber smarts, to still be using an unsupported Windows 7: https://healthitsecurity.com/news/fbi-operating-windows-7-increases-cyber-risk-to-network-infrastructure

For those who, like myself, have no wish to ever have the new interface forced on me with no option to disable, may I recommend removing the current version and then installing from the so-called "Classic Track" ? I have successfully installed Adobe Acrobat Pro 2017 (Classic Track) [the last version to support Windows 7, which I use for reasons identical to those for eschewing the most recent Adobe Acrobat release), I have disabled auto-updates, and if the Adobe prose is accurate, I am now safe for life :

The Acrobat product family provides two tracks for both Acrobat and Reader:

The Continuous track provides service-based tools as well as new features, security and platform enhancements, and bug fixes as part of frequent (and most often) silent updates. Over time, the Continuous track’s update cadence will be more frequent than the Classic track. Classic license program customers do not have access to this track for Acrobat.

The Classic track is similar to the 11.x model and provides few (if any) new features in updates. Like previous releases, a quarterly update cadence delivers security and platform enhancements as well as bug fixes.

So seeing that Adobe are not listening to anyone's comments or feedback other than a "sorry, not sorry" comment... Just what are the alternatives that are out there that people are finding? lets at least use this platform to support each other for a solution.

I quit using it 10 years ago after this debacle:
https://community.adobe.com/t5/acrobat-discussions/acrobat-dc-so-horrible-it-s-making-me-want-to-cry/m-p/7112345

I'm really only here for the spectacle. Sorry to the millions of users who have not yet been able to switch and have to put up with this 𝗗ismal 𝗖rap software every day.

I quit using it !

Honestly, I think the only way to get Adobe's attention is to quit using their product altogether. I'm not sure if this isn't what they want. Collect royalties for using the PDF engine with no programming staff? Or put a full effort into Acrobat and make it nice. I think Adobe only wants the easy money.

I am looking at alternatives every day. There are some good windows products out there. One is made specifically for architectural projects.

You forgot to mention the missing scrollbars the just "show up" once in a while. This is total ****. I don't want to find an icon top "pan." The scroll bars are way more convenient. Anything else you think you can ***** up, Adobe? There isn't much left!

I only wish I could write as unemotionally as you!

Nobody has mentioned that this program was originally written for a Mac, but now won't run worth a darn on one. 😉
