Q: I tried to download software and used your instructions, but I can't get it and the following message (or similar) is displayed:

ftp> cd HEG_Tool
... permission denied...

A: Unfortunately, sometimes our server goes down. Try again in a few hours. If you still have problems, let us know and we will check it out.

Q: Do I need JAVA installed?
A: Yes, you'll need version 1.6 or higher.

Q: Do I need any other software besides JAVA and the HEG TAR files?
A: No, Everything else you need is inside the TAR file.

Q: For Windows, do I need to install Cygwin?
A: No. The Cygwin DLL is included in the installation. If you already have Cygwin installed, you may have a conflict with your present Cygwin DLL. You can temporary disaable (one way is to rename it) the one in your /bin directory. This will allow the one in the HEG package to be used.
