Download the patch at the bottom of this page: 

http://www.altera.com/education/univ/unv-index.html  Now, ignore the instructions on that page, they don't apply to 14.0  First copy C:\altera\14.0\quartus\bin64\cygwin To C:\altera\14.0\quartus\bin64\cygwin.old (To make a backup copy in case something goes wrong)   Extract the files from cygwin_patch.zip to somewhere like your desktop or downloads folder, then copy the contents of the 'bin' folder (NOT the bin64 folder!) to: C:\altera\14.0\quartus\bin64 Merging folders and replacing any files.  The error should have gone away.
