No longer able to change scale ratio on Acrobat Reader

Hello all, I have been having the same problem, I have been through all the replies to this thread and have not found a resolve, if anyone can offer some help it would be grealty appreciated..

None of the proposed solutions worked for me,not disabling the new adobe or the workaround by Jason38816712in5k (although these seemed to work for a lot of people). What did help me:

Measuring tool > Make and lock a measurement > Select the measurement so there's a blue box > Right click outside the box > Selecting "Snap to page content" from the dropdown menu.

Then, remake and lock a new measurement > Select the measurement so there's a blue box > Right click outside the box > Magically, the "Change Scale Ratio and Precision" appears. 

Idk why it worked, but it did. Now I don't have to rage throw my laptop into a wall. Happy new year!

for non mac users, what's the solution to this problem?

Go to left menu and choose view more

go to Measure objects and click left key twice

then change scale ratio

Hopefully this doesnt trigger a fix from adobe, but ill share what worked for me. I'm on a macbook pro (sonoma 14.5) with an external trackpad and docking station. And using adobe reader.

Open a normal pdf file in reader. Go to left, and select the Measure Objects option.

When you do that, a floating toolbar (for me anyway) opens up and says Snap Types and Measurement Types at the top (right for me, maybe different for you). In that box, I click on the distance measuring length tool (also perimeter tool works). ANd I made a measurement using three clicks (one to start, one to end, and third to anchor the line that shows the length of the measurement). Hover your mouse over that measurement until your mouse goes from a cross to an arrow, indicating you are about to click on that line and change its settings. Right click on that line and you get a dropdown that starts with 'Reply', and the line will then be surrounded by a box. Dont click any of those options (and keep that option window open), but move the mouse off of that measurement and outside of that box that is highlighted, surrounding that newly measured line that you made. then right click anywhere on that PDF that is NOT on that box. Once you right click, you should see the familiar dropdown box that starts with: Change Scale Ratio and Precision. Good luck!!

I found an option in the left corner settings drop box which i think was listed as" disbable the new adobe experience "  This has taken me to an old version with the tool repaired.

File -> disable new acrobat reader

Worked for me.

Hello All!

I hope you all are doing well, and we're sorry for your trouble.

Please try the registry settings below and let us know if they work for you. Please ensure you take a backup of the existing registry before making any changes. For more info on backing up on Windows, see this article. For Mac, see this article.

MAC :

Path: ~/Library/Preferences/com.adobe.Reader/plist

Registry:  DC/FeatureLockdown/bNewMegaverbRCMExp(boolean) = True

WIN:

Path :

• 32 bit: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Policies\Adobe\Adobe Acrobat\DC\FeatureLockDown\
• 64 bit: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Adobe Acrobat\DC\FeatureLockDown\

Registry : bNewMegaverbRCMExp(REG_DWORD) = 1 (to disable)

I hope this helps.

Thanks,

Anand Sri.

SOLVED!

I encountered the same issue and resolved it by following these steps:

1. Go to File.
2. Select Disable New Acrobat Version.
3. The application will restart, reverting to the old version, which is more stable and less buggy.

This worked on Windows 10 with Adobe Reader 64-bit. Good luck!
