The Microsoft® Windows® installer is a self extracting executable named BayES_WinXX.exe, where ‘XX’ could be either ‘32’ or ‘64’, for 32-bit and 64-bit machines, respectively. To initiate the installation process double-click on the installer and accept any prompts from the system. After extracting the contents of the archive you should be able to see the ﬁrst page of the setup wizard (see ﬁgure below). From now on you should follow the instructions on this wizard:
Click on the Next> button on the welcome page of the wizard to proceed:
Read the license agreement and either check the “I Agree" checkbox and click Next> to proceed or Cancel to cancel the installation process:
On the next screen you need to provide the location where BayES will place its system ﬁles (libraries, icons, initialization ﬁles, etc.), documents, datasets and sample script ﬁles. The location provided must exist on the machine’s ﬁle system and the user must have write access on it. If a location is chosen for installation on which you do not have write permissions (for example C:\Program Files), the installer will issue a warning and a prompt to either:
pick a diﬀerent installation location, or
quit the installer and rerun it with administrative rights1
When BayES is installed in a system folder, users without administrative rights will not have permission to alter any of its ﬁles. This is reasonable for most purposes, as it keeps BayES’ system ﬁles secure. However, a user without administrative rights will not be able to make persistent changes to the initialization ﬁles (for example, to store his/her preferences regarding prompting to save ﬁles on exit or specify the location of external binaries). If a system administrator wants to make such changes then he/she should run BayES as an administrator.
There are three additional options available on this page:
- if the ﬁrst checkbox is checked the installer will attempt to create a shortcut to the BayES executable on the system’s desktop
- if the second checkbox is checked the installer will attempt to create a shortcut to the BayES executable on the system’s “start" menu
- if the third checkbox is checked the installer will attempt to make BayES accessible from the command line. This means that BayES will be available from the system’s shell by typing BayES, optionally followed by a script ﬁle to be executed.
Finally, click on Install to get the installer to commit changes to the system.
Once the installation completes you should see the following screen. Look at the install log on this page in case something went wrong during the installation and act accordingly. Click Close to quit the installer. If everything went ﬁne you should now be ready to use BayES.
1To run the installer with administrative rights right-click on the BayES_WinXX.exe ﬁle and pick “Run as administrator" from the pop-up menu.
