In more recent versions of Windows (version 7 onwards) it is common to be prevented from downloading any files into the 'Program Files' folder, and even if you overcome this by running 'as administrator', problems will occur later. It is strongly recommended that the BugsXLA files be extracted to a folder immediately beneath the root C: directory, e.g. C:\BugsXLA7. You may also encounter annoying error messages on running WinBUGS if this package is located beneath the 'Program Files' folder. My solution is to save WinBUGS to C:\WinBUGS14. OpenBUGS does not appear to have this problem.

The files can be downloaded in .zip format: Version 7 and Version 5
Be warned: Microsoft's default setting is to be very cautious with .zip files, and so you may be prompted to enable macros everytime you use BugsXLA.

If you do download BugsXLA, I would be very grateful if you would send me a brief email with the following information:

• Your location (country and nearest city)
• Primary application area for use of BugsXLA

Subsequent to you using BugsXLA, further information would be of interest, eg whether you found the program useful, suggestions for improvements and notification of any bugs. I promise I will not pass on your email address.

Please consider joining the BugsXLA Google Group where users can share their experience, raise issues and offer solutions. In future I will post my responses to queries there, as well as keeping users aware of any further work on the program.
