Saving won't update original file, instead forces you to create a new file.

[ShahrierH10]

I am currently using Adobe Acrobat Reader DC (17.012.20098) on Windows 10 Home. Both are completely updated as of 9/23/17.

When I open a pdf and edit it using comments or highlights etc, I have difficulty saving. When I hit the save icon (or go through  File -> Save), it won't update the original pdf. Instead it makes it go through the save as process and create a new file altogether. I can save over the original file, but it's kinda annoying to have to go through this every time.

Hello ShahrierH,

Sorry for the delay in response to your query and apologize for the inconvenience caused. As per the description above, you are not able to save a PDF file after editing as it creates another PDF file and does not update the original file, Is that correct?

Please repair the installation files of Acrobat Pro DC from Help>Repair Installation. You can also reset the Acrobat preferences, to reset the preferences refer to How to reset Acrobat Preference settings to default.  Link: https://forums.adobe.com/docs/DOC-8511

If the issue still persists, then remove the Acrobat Pro DC using the Acrobat cleaner tool Download Adobe Reader and Acrobat Cleaner Tool - Adobe Labs  Link: http://labs.adobe.com/downloads/acrobatcleaner.html

Restart the computer, and then install the Acrobat back from Download Pro or Standard versions of Acrobat DC, 2017, XI, or X  Link: https://helpx.adobe.com/acrobat/kb/acrobat-downloads.html

Hope this helps, and let us know how it goes.

Regards,

Anand Sri.
