"save as" pop up box does not allow me to save the document.

Thank you. The solution below from richil on 14th May 2015 still works.

Thank YOU SO much. This was an easy fix thanks to your insight

This worked!

Here's what the window looks like if anyone wants to know.

The Format drop down menu disappeared after reinstalling on a new computer running High Sierra.

I don't have the items to check off in the General pane of the preferences of Acrobat X1 Pro ver 11 so I still can not fix it.

I might have to reinstall.

BTW, the Format drop down menu DOES show up in the newer Acrobat Pro DC (Build: 18.11.20055.290043). See 2nd image attached below.

Brilliant - solution worked a treat, my sincerest thanks

Thank you! Turning off that feature did work... God Bless You!!!

This worked for me

OMG thank you so much Adobe Guru - your instructions worked!!! I have been trying to fix the same issue for almost 6 months. Even called our IT guy and even he couldn't figure it out. On Windows.

I was working in Adobe X 10.1.16 on Mac OS 10.12.6 and 10.13.4 with the same problem using a Mac Mini File Server running OS X 10.8.5 and Mac Server 2.2.0. Users were having to save documents to a 'dummy' location before being able to save to their original location folder. This occurred when making a quick change and save or when they wanted to add a revision to or change the title (R01, R02, etc).

It didn't matter if the original file was on their desktop or on the network drive.

The workaround (which only saved one step) is that you don't have to physically SAVE the document at all. When it asks you where you want to save, you just have to go to a different folder, then go back to the original folder you want to save in. Not sure if it has to be a separate drive altogether or just a different folder on the same drive.

So, if you were on your desktop, and you were getting the error, when you do a Save As or when it asks you to save, you must select 'documents' or 'downloads' first, then go back to desktop to save the document. (If you're using the same name it will ask you to replace, as usual).

I actually have Adobe XI, so I wasn't having the issues until co-workers brought it up who were using Adobe X. I'm dreading the upgrade, to be honest.

It worked for me.
