I had a running system with Miktex 2.9 and Biber as well as Texniccenter 1 on a W7 machine. Now I bought a new W7 machine and wanted to reproduce the system on this machine. I installed the same Texniccenter version and the latest Miktex 2.9.5105. I also downloaded Biber from here and moved it to C:\Program Files (x86)\MiKTeX 2.9\miktex\bin.
I then exported the output profiles from my old Texniccenter Installation and imported them in the new one.
The problem now when compiling on exactly the same .tex-files (after having deleted all the stale AUX-files etc.): I don't get any errors, but a lot of warnings. Basically, all my references seem to be undefined. E.g.: Latex warning: citation 'oreilly_2005' on page 92 undefined on input line 201.
I also went into the Settings and Settings (Admin) of Miktex and "refreshed the FNDB", didn't help.
I don't understand what the problem is, as, apart from the new Miktex (and probably biber version), everything is the same as on the old machine.
Do not run bibtex with this projectetc.? Also do you see Biber firing up some logging comments in the log file? – percusse Mar 05 '14 at 07:03C:\Program Files (x86)stands for 32-bit programs in a 64-bit Windows … – Speravir Mar 06 '14 at 00:24
