I have a problem in TeXnicCenter. So I have built the .tex file with Ctrl+F7. I have 0 errors, and now how can I generate the PDF file? That button - Build Output (F7) is disabled. Why?
When I press F5 I got the error from the image:

We had this problem a lot with the stable builds of TeXnicCenter, and as a result, I've never trusted Adobe Reader and DDE. It might be improved with TeXnicCenter 2.0alpha3, but when we started testing the alphas, we just pointed them all at SumatraPDF.
In our LaTeX => PDF build profile, Viewer tab:
Executable path:
C:\Program Files\SumatraPDF\SumatraPDF.exe -inverse-search "\"C:\Program Files\TeXnicCenter Alpha\TeXnicCenter.exe\" /ddecmd \"[goto('%f','%l')]'\""
View project's output, DDE command:
[ForwardSearch("%bm.pdf","%Wc",%l,0,0,1)]
View project's output, Server: sumatra, Topic: control
Forward search, DDE command:
[ForwardSearch("%bm.pdf","%Wc",%l,0,0,1)]
Forward search, Server: sumatra, Topic: control
Close document before running (LaTeX): Do not close
You could greatly simplify the above if you don't need to jump back and forth between the PDF output and the source files. But the best thing about Sumatra is that you can keep it open and it will pick up on PDF changes when you rebuild. We never got our installed versions of Adobe Reader to close consistently via DDE.

<pre>...</pre> tags is recommended to avoid wrong syntax highlighting.

Hit Alt+F7 and set viewer preferences according to the example. It works with win7 and Adobe 11.

I think Adobe changed the name of the DDE Server name for new Acrobat Reader versions. I think you need it to be AcroViewR10 instead of acroview.
In TexnicCenter press Alt+F7 to edit the profiles. Click on Latex -> PDF, and click the Viewer tab.
Changing the server worked for me as well. I am using Reader 11.0.
I did the following:
