If I change the True TYpe Font folder to directly point to c:\\windows\\fonts I get the following:
 
PDFWriter: Unable to successfully read the font from 'C:\\Windows\\Fonts/tahoma.ttf'.  This font will not available.  Internal error code was '6'
PDFWriter: Unable to successfully read the font from 'C:\\Windows\\Fonts/tahomabd.ttf'.  This font will not available.  Internal error code was '6'
PDFWriter: Unable to successfully read the font from 'C:\\Windows\\Fonts/tahoma_0.ttf'.  This font will not available.  Internal error code was '6'
PDFWriter: Unable to successfully read the font from 'C:\\Windows\\Fonts/taile.ttf'.  This font will not available.  Internal error code was '6'
PDFWriter: Unable to successfully read the font from 'C:\\Windows\\Fonts/taileb.ttf'.  This font will not available.  Internal error code was '6'
 
What is internal error code 6?
