Adobe Acrobat X crashing a few seconds after being open

If the other FTP links aren't available, you could try this official Adobe source with alternative FTP links, for both Mac and Windows updaters to Acrobat version 10.1.16.

On my Mac with the launch crash on OS 10.13.6, the simplest thing was to clik on the link below, connect as "Guest", clik on the server in the left-hand column of the finder window. This shows the files on the ftp site. Open 10.x folder, then 10.1.16. folder, then Misc folder. Drag the AcrobatUp10116.pkg to the desktop. From there, double clik and follow instructions. Done.

I just updated Acrobat Pro X as well for Windows, using "check for updates" as soon as the app opened. It worked!!! Thank you to those who suggested this idea! 

It is not that bad pointing users to ftp link where to find all sorts of folders, above all some file required actually being  .msp file. Easy for  some tech savvy to install, right? But for someone who just want their damn Acrobat to stop crashing due to update issues or end of life support issues, all they need is some clear help from this community.

Having said the above, for anyone still facing this issue, you may quickly launch acrobat and before it crashes, under *Help* button in the menu bar, last iterm is *Check for Updates*, you will get lucky and your system will pull the damn 10.1.16 update and start to install automatically. Your problem might be solved! 

I had this problem and tried a ton of different fixes. Finally got Acrobat X to stay open without crashing. 
I'm not sure if it was a single fix or a combination that did it, so to be safe I'll list all of them, starting with most recent.

For a lot of people, attempting to click help - update worked, but I don't have that option. I have repair installation but it didn't work. I'm on 10.1.2 and never did figure out how to update it.

Here's what I did:

• Went into my list of services (click start, type services.msc) and found Adobe Updater service. Stopped and disabled it.

• Unchecked "show me messages when I launch acrobat" under preferences, general.

• Disabled "Enable enhanced security" under preferences, security (enhanced).

• There may exist in other versions a similar security setting, 'launch in protected mode' which I've disabled in the past to work around various problems.

• Run regedit, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Policies\Adobe\Adobe Acrobat\(version)\FeatureLockDown, create a new value called bDisableFrequentSignInWorkflow (reg DWORD), set the value to 0.

• In the same area of the registry, FeatureLockDown, create a new key called cServices (new key means new 'subfolder' under FeatureLockDown). Within that key (on the right) create a new value called bToggleAdobeDocumentServices. Set this value to 1. Then create several other values.

bToggleAdobeSign (DWORD, set it to 1)
bTogglePrefSync (DWORD, set it to 1)

bUpdater (DWORD, set it to 0)

This last one might be crucial. If the crashing is caused by an attempted update or failed update, I think the last registry entry tells acrobat to not attempt updates. It might be that you need both that reg. entry and also to disable the update service.

Hope it helps others. 

Thank you so much. I tried so many things and had the same problem of my Acrobat Pro quiting in my CS6 Master Suite version and this link fixed it. It did say that it was an outdated certificate, but regardless the bottom line is that it fixed the problem...fabulous!

You should start by installing all available updates up to 10.1.16, which is the latest Acrobat X version released.

You can find them here: ftp://ftp.adobe.com/pub/adobe/acrobat/mac/10.x/

Keep in mind that Acrobat X is an old and outdated application, not compatible with any current OS, including yours, so problems are to be expected.
