[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.)

What do our Customers say about us?

I have had a very helpful response, and have passed it on to my Oxford colleagues with success. I am impressed with the way Adept seems to maintain the same staff for many years, which speaks very well for the organisation.

HG, Oxford, UK

Adept are continuing to be the most reliable and effective of all the technical helpline staff that I encounter.

MD, Worcs, UK

Your website is hugely informative and a pleasure to visit. Frankly I wouldn’t dream of buying technical software from anyone else.

NR, Inverness, UK

I greatly appreciated the fact that you did what you said you would do – not everyone is so nice and punctilious as you.
