[1]: The program uses a 16bit installation and 16bit ED Editor, neither of which are compatible with 64bit Windows. (However, Windows7 Professional and higher edition users can install a Windows add-on called Windows XP Mode, and then the Lahey compiler can be installed within this environment. XP Mode is not available on Windows 8, but a virtual machine could be used.)

[2]: If only the F95 Win32 compiler is required, choose to install the compiler only without Visual Studio .NET and ignore any licence activation error. No editor will be supplied, but the compiler will function OK within the Command Prompt. If the .NET compiler and/or VS2003 are required, the installation is non-trivial but may be accomplished after reading the following two forum threads: http://www.laheyforum.com/showthread.php?t=10692 and

(Windows7 Professional and higher edition users can also install Windows XP Mode as mentioned above. Windows 8 users would need to use a virtual machine.)

I am impressed – somebody actually cares enough about customer relations, not only to honour a promise to reply, but to remember the request! I hope your company appreciates you as much as I do.

Origin lets you zoom in on an an area of the plot easily without having to rescale manually. I also love the data reader feature where you can follow a line or curve and view the exact coordinate values. Thanks for an awesome product!
