I had a similar issue with VS 2012 Express. I used Tesseract libraries in my project. Everything worked well until I used this project in a solution where were more than one project. Problem was that some DLLs (liblept168.dll, libtesseract302.dll) that are normally placed in folders bin/debug/x86 or bin/debug/x64 were copied only when I rebuilt whole solution. Changing a single line and building it again caused that the DLLs were deleted and not copied back.

I solved this issue by adding a reference of the project that creates missing DLLs to the startup project.
