I have followed the answer posted by Moderator Mitch user 59676 and created mpe.desktop file, right clicked on the file and 'open with other application' - 'show other applications' did not list master PDF editor so unable to make as default.

I want to make Master PDF Editor (MPE) the default for opening PDF files. I right-clicked a PDF file, chose Properties > Open With. MPE was not listed. I clicked Show Other Applications but MPE was still not on the list. I tried opening the PDF file with MPE, editing, and then closing it. MPE still did not show up.  So how do I make MPE the default program, or at least appear on the Other Programs or Show Other Programs?

How can I change or set the default application for handling a given file type? What about for some specified actions, like "open web browser" and "preview image"?

I seem to be having issues when I try and save the output file as a .png, or .jpeg for that matter. I've set up my user preferences, File, Render Output to my desktop as well as render output in the editor window. What am I missing here? I'm obviously very new to this program and your help would be appreciated. Thanks for your time

I used to work on the Mac terminal before and I used:   open file2open.pdf   and the PDF file would be opened on preview or whatever my default viewer was. When I use it in the terminal in Ubuntu I get this error message:   Couldn't get a file descriptor referring to the console

Do you know a good way to compare PDF files side-by-side and show the modifications between the two?  I'm looking for Windows software to accomplish this. It would be great if you can post both free and not-free products.

I already tried Adobe Acrobat, Adobe Acrobat Reader and Sumatra PDF but all doesn't work..  The first time if I use latex -&gt; pdf output profile it works. But if something is changed I still get the same PDF. If I then delete the PDF I get in Adobe Acrobat      this file cannot be found   Settings:   Path of executable: C:\PROGRAM FILES (X86)\ADOBE\ACROBAT 10.0\ACROBAT\ACROBAT.EXE   Command line command:   "%bm.pdf"   Forward search the same.   Also tried:   DDE command: [DocOpen("%bm.pdf")][FileOpen("%bm.pdf")]   with server:    acroviewA10, topic: control   (according to )  Who can help?  UPDATE: It seems that the miketex setting: install packages on the fly was causing the problem. I changed the setting from install packages on fly from "ask me first" to "YES". Now the pdf's are produced. The pdf reader opens and closes really fast however..but I can make pdfs! (took me several hours to fix this..)..

When having a number of files opened in Texmaker, at the top of editor pane, there is a drop down panel with the names of open documents in it. I prefer to have tabs of open documents at the top of editor pane, similar to Texstudio and Winedt. Is there a way that I can change this setting?

My friend who has only recently downloaded blender has come across a workspace issue. He said he accidentally pressed a button and it has entirely changed his user interface/ Workspace. He can't open, save or do anything with the change.    This is a full window image!

Every few days the file association for PDFs on my Windows 10 machine switches to Microsoft Edge.  I then right click on a PDF, choose "Open With -> Choose Another App", select Acrobat from the list, and check "Always use this app to open .PDF files".  Then for a few days it sticks, but always winds up going back to Microsoft Edge.  I haven't figured out a pattern to suggest when/why this happens.  It just does and is very annoying.  Does anyone have an idea of why this happens or how to permanently fix it?

Although there are several posts on the Internet on the subject, I did not find a solution yet: my goal is to find a command that adds an icon (.desktop file) to the Unity launcher and shows it immediately. when I open dconf-editor (desktop > unity > launcher) and I add an item to the favorites list, it shows at once in the launcher, so my idea is that it must be possible to do the same thing by command. The solutions I found so far on the Internet do not do the job.    I need to do it by command, to use in a quicklist editor I am working on.  You would make someone unbelievably happy if you could help out

Similar to the way Notepad++ adds "Edit with Notepad++" to the context menu of all files, or how most Antivirus products will add a global "Scan this file" option, I would like to add a particular program to the context menu for all file types.  Thanks to DOSBox, I'm a little familiar with manually creating file associations and creating context menu options for specific file types.    However, I've got one program I'd like to add as a context menu globally because it can be used with files that have almost any extension.  What registry keys do I need to modify for this, and what common pitfalls should I avoid in order to not break things here?  I'd rather do this manually, so that I'm intimately familiar with what changes I'm making to the system, rather than use a third-party tool.  The OS I'm doing this on is Windows 7 x64, but it would be great if the same method could be used all the way back to XP.  I can probably figure out the necessary command syntax myself - I just need to know which keys to go after and how to format the commands and labels to be properly recognized in those keys.

I'm running the default pdfjoin and getting results like this:    How can you pdfjoin different sized pictures? My first idea is to add an empty page in front of all things.

If I download a PDF in Chrome (even from Drive), on any platform, and click on the downloaded-file-button down the bottom, the PDF opens in Chrome in a viewer that includes a table of contents browser, smart zoom controls and other features.  If, on the other hand, I double click on it in Drive, it opens in Chrome but in a preview style viewer that is very limited, with none of the features above.  How do I get Chrome to open PDFs from Drive... well, in Chrome?

When working with PDFs, I've run across the MIME types application/pdf and application/x-pdf among others.   Is there a difference between these two types, and if so what is it? Is one preferred over the other?  I'm working on a web app which must deliver huge amounts of PDFs and I want to do it the correct way, if there is one.

Online it says I should be able to find pdfedit in the software center. That doesn't work for me. I've tried many times. Is there any other way to install pdfedit or master pdf edit on ubuntu 12.10.
