Altera Monitor Program Error in Win8

Probably I've found tyhe solution:I've downloaded the cygwin new release (both the 32 and the 64 bit) and I've used them to substitutethe cygwin software delivered with quartus.Moreover remember to include during the installation of cygwin the "perl" utility.

Thanks for this info - I'm also getting the warning: couldn't compute fast_cwd pointer problem on Windows 8.1.I found that the default install for cygwin doesn't include gcc or g++ so you also have to include the devel package in the installation options (or at least some of it, the whole devel package brings the cygwin install up to 4GB, which is quite a lot and not really necessary).
