My computer uses English. I am using the latest version of libRDPDFLib.a released yesterday(08-oct-2013) but still the problem persists.
I found no folder named 'Microsoft' under the font "/library/fonts/" and I think that is not an issue. I can able to run the demo provided by you without any issues. I followed the instructions given in the help.pdf and can able to successfully implement the pdf viewer in a new project. But when I tried implementing your library into my existing project, the problem occurs. kindly provide a solution as soon as possible.
