DDE control TeXnicCenter

I use TeXnicCenter for LaTeX and would like to have the DDE controls working to easily view the pdf versions. Acrobat X seems to have changed the servername and this is breaking things. I tried "AcroViewR10" or "acroviewR10" and other combination, but still it does not work.

As a work around, using command line argument "%bm.pdf" works, but I manually need to close the pdf everytime before recompiling. So, it takes an extra click or so.

Can anyone give some insight to solve the problem either by fixing DDE or how to close the pdf automatically when it is recompiled?

Actually, the answers from Martyn and Adam Nellis solved this problem. Thanks a lot, folks. I am just putting it step by step, so someone else can use it.

Step1: Adobe ReaderX In Adobe Reader X, go to Edit>Preferences>General and uncheck "Enable Protected Mode at startup".

Step2: TeXnicCenter Go to Build->Define Output Profiles-> choose "Latex to PDF" -> Viewer tab

2.1. For "View Project's Output" & "Forward Search"

• Command: [DocOpen("%bm.pdf")][FileOpen("%bm.pdf")]
• Server: AcroViewR10 Topic: control

Later NOTE: (the numbers change per version and exe)

• For 32bit AcroRd32.exe the Server will be AcroviewR##
• For 64bit Acrobat.exe the Server will be AcroviewA##

The use of capital letters may not be important, but the number is.

Where ## will be your current version 10,11, ... 19,20,.....24,25,26 etc. For other suggestions see https://tex.stackexchange.com/questions/250472/texniccenter-adobe-reader-dc

Thus the following advice may be wrong as the DDE server includes the version number from the registry. See the locations as given towards end of Martyn's answer

2.2. For "Close Document"

• Command: [DocClose("%bm.pdf")]
• Server: AcroViewR10 Topic: control (use this option even if you use Adobe Reader 11)
