Adobe Acrobat Pro DC crashes when I combine PDF's

Please check the length of file name of documents to be combined. Just fixed mine, there's a need to reduce the length of the file name.

1. From Microsoft Word go to File>Options>Addins>Com Add-Ins>Go
2. Fully remove and readd the Adobe PDFMaker addin from this location (If you just redirect the addin without fully removing may still have issues):

         C:\Program Files (x86)\Adobe\Acrobat DC\PDFMaker\Office then select “PDFMofficeAddin.dll”

    3. Hit “Ok” twice to make sure the addin location saves.

Something that I noticed in uninstalling Acrobat DC is that unlike other CC apps, DC doesn't ask if you'd like to delete or keep the application preference file. Could there be a preference file in the Library directory that needs to be manually removed before and or after reinstalling the software?

I'm having the same issue. I am trying to insert blank pages using the add   icon within the organize pages function of Acrobat DC into a 122 page pdf document. The strange thing in this is that i've already edited this document adding blank pages in Acrobat DC and didn't have an issue with added pages until recently. The last time I worked with this same file was around March 2016. 

Adobe Acrobat Pro DC crashes when combining pdf's.

It just started doing this a few days ago.

I have repaired the install.

I have re-installed and it keeps doing this.

Is there an update or patch

I am using Windows 7 Ultimate

This is the error message:

I found an old version of Acrobat Professional and thankfully it works fine, Combined all my high-res pdfs without any problem whatsoever. So why can't Acrobat DC do this? Where's the update?

Having the same issues -- since the most recent update with creative cloud, constantly crash when I try to combine documents; very alarming given the importance of this feature. Any updates on the fix?!

Same problem!!!!!

Same here.  Win10, Office 2016, Acrobat DC.

Cannot combine a combination of PDFs and Word files.
