bottom line: I compiled and linked to doublefann.c directly (included it in the project and #define FANN_NO_DLL), and it works fine. So the "bug" is with the VS2010 project settings that create the DLLs. Case closed but you may want to revisit the VS2010 build flags for double precision

PS. this is not idle bug reporting. On (most?) windows x64 systems, working with "float" numbers could be 3 times slower than working with "double" precision, especially for 32 bit applications. So if the double version of FANN is buggy, then all the professed "speed advantage" is gone!

I am building the sample FANN projects (latest version 2.2) with visual studio 2010. When using floats as fann_type it works ok, but if I switch to doubles (include doublefann.h instead of fann.h) there are access violations in large networks. I discovered you can also see the bug with small samples like XOR_TRAIN included in the examples folder. Build it as it is (using floats) and mark the output. Then switch to doubles (#include doublefann.h and link to fanndouble.lib) and see the output is different...

I've just installed NAPS2 latest version on an old windows XP.SP3 (I had to download .NET v4). It works. but when I click on OCR button and try to download any language (even english) it fails!? It says download failed without much details. Internet connection is fine
