Acrobat Pro DC - Combine PDF files stops working after a few times

Hi there 

We are sorry for the delay in response and the trouble caused 

We need some more info for better understanding

• What is the version of the Adobe Acrobat DC you are using? To check the version go to Help > About Adobe Acrobat /Reader DC
  Make sure you have the latest version 20.006.20042 installed
• Is this a behavior with a particular PDF or with all the PDF files? Please try with different PDF files and check If its a file specific issue please share the file with us for testing.
• You may also try to reset the preferences to default as described (https://community.adobe.com/t5/acrobat/how-to-reset-acrobat-preference-settings-to-default/td-p/4792082?page=1)

If it still doesn't work 

• Remove the application using the Acrobat Cleaner Tool (https://labs.adobe.com/downloads/acrobatcleaner.html)
• Reboot the Computer
• reinstall the application using the link (https://helpx.adobe.com/in/download-install/kb/acrobat-downloads.html)

Hello Paulforde,

We're sorry for the delayed response and inconvenience caused. Is Acrobat is freezing or crashing while using the Combine PDF feature?

Please check for any pending updates of Acrobat installed from help>check for updates, reboot the machine after updating Acrobat and try combining files.

Reset the Acrobat's Preferences once and see if this makes any difference. To reset the Preferences, refer to the article How to reset Acrobat Preference settings to default.

Is it a Mac or Windows machine and what is the version of OS installed?

What is the dot version of Acrobat installed? To identify refer to Identify the product and its version for Acrobat and Reader DC

Let us know how it goes and share your observation.

Thanks,

Anand Sri.
