Merge files in Acrobat doesn't work

Question

I want to merge several pptx files in Acrobat using the Merge tool in Acrobat. The tool opens, but does not display a preview of the pptx files. When I select Merge, the program starts but then closes with the message “No PDF file was created due to an unknown error found by Adobe Acrobat.” It works on another computer. Do you have any ideas?

Hi there

Hope you are doing well and thanks for reaching out.

Is this an issue with a particular PPTx file or all the files? Please try with a different PDF file and check.

What is the workflow/steps you are taking? A small video recording of the steps and the issue as it occurs would be very helpful. Also make sure the Acrobat application is updated to the latest version 25.01.205XX go to Help > Check for Updates and reboot the computer.

Also try to combine the PDF online here https://adobe.ly/4kUg4AC and see if that works.

Let us know how it goes.
