Can't update Adobe Acrobat Pro DC (2015)

(I checked: 2015.006.30527 was the final update for version 2015, so you have gone as far as you can with free updates. )

If the fix was issued after Acrobat 2017 was released, you cannot apply it to Acrobat 2015, you need to pay for an upgrade to a newer version. Your software was superseded almost 4 years ago.

Hi Leem 

We are sorry for the trouble. As described the application is crashing on scanning.

What is the workflow/steps you are doing to scan the document? Also, please try to scan a different document to check if its a file specific issue.

Do you get any error message when you try to scan? If yes, please share the screenshot of the same for a better understanding.

Please try to reboot the computer once and try again and check.

You may also try to repair the installation from the help menu and see if that makes any difference.

If it still doesn't work, for testing purposes, please try to turn off the protected mode for testing. Go to Edit > Preferences > Enhanced Security > Uncheck 'Enable protected mode at startup', turn off the protected mode and uncheck the enhanced security > Click OK and reboot the computer.
Note: Turning off the security may possess security risk. Please turn on the security after testing.

You may also try the steps provided in the help page https://helpx.adobe.com/in/acrobat/kb/acrobat-dc-crashes-on-windows-os.html

If it still doesn't work please try to create a new test user profile with full admin right on Windows and try using the application there and check.

I'm running Acrobat 32-bit on my HP Windows 10 64-bit computer. Could that be the problem?
Acrobat DC is compatible with Windows 10 (32 bit and 64 bit). For more information please look at the help pages listed below:
