LF Fortran  

Installing LF95 Only

The LF Fortran installation package is available for download from www.lahey.com.

Note: When installing on Windows Vista ©, Windows 7 © or newer, User Account Control (UAC) may occasionally display a permission dialog that is hidden behind other dialogs on the desktop. This may happen if you look at some other window, and the installer dialog loses focus. You can tell this is happening when the UAC taskbar item is flashing, and the installation dialog seems to be in a wait state. Clicking on the taskbar item will bring the UAC dialog to the front, and installation can continue when you dismiss the dialog.
