Dyalog APL Conference 2022 Edition (V120.22): Installation READ ME FIRST

This conference edition (V120.22) is released under the non-commercial licence; it should not be used for production. We suggest that you use it only to investigate the features which John Daintree mentioned in his presentations which are available at Dyalog TV. We offer no support for this version, but we would be interested in any feedback you have. This edition is currently available only as 64-bit Unicode for Microsoft Windows.

If you already have Dyalog APL installed on your Windows PC the installation process will pick up the serial number from your existing installation. If you do not already have a version of Dyalog APL installed on your Windows PC then simply leave the serial number field empty. This conference edition will not alter any file associations.

The contents of this version and the installation process is similar to any other version of Dyalog APL on Windows: if you have installed on Windows before, you will be able to install this version in exactly the same way !

V120.22 will co-exist with any other version of Dyalog on your machine; there is no need to uninstall any existing version. Just remember that you cannot )load workspaces created by later versions - so any workspace you create in V120 will not be loadable by 18.2 or earlier !

Dyalog V120.22 can be installed either with administrator rights, or without. Dyalog Ltd strongly recommends that whenever possible, the installation is performed with administrator privileges.

An installation performed without administrator privileges has the following limitations:

• The APL 385 font is not installed. Dyalog V120.0 will use the APL385 font, but no other application will do so.
• The IME is not installed. Instead the keyboard is defined as a series of Registry entries. This means that the keyboard cannot be used in anyh other application.
• No attempt is made to install the VS2015 redistributables globally; they are therefore not available outside the interpreter unless they have been installed beforehand.
• A non-administrator install is available only to the user who performed the installation; on a shared machine all users would have to perform a non-administrator installation.

Note: Dyalog strongly recommends that if not already installed, you include the VS2015 runtime packages when you install Dyalog APL; failure to do so may result in the failure of .Net-related code.

Note: the installation of Dyalog APL will require a reboot of the system to be fully effective !

To perform a default installation of Dyalog APL with administrator privileges:

1. Extract the contents of the downloaded zip file into a temporary directory
2. Double click on the newly extracted setup*.exe (you are probably reading this having taken these two steps !).
3. Select "Yes" to the question "Do you want to restart the installer with Administrator privileges?"
4. Select "Yes" in the User Account Control pop up. Note that this Msgbox may hide behind other windows !
5. Ensure that the Unicode IME is selected.
6. Click on Default Install.
7. You must accept the Licence terms which will appear in a pop-up window to continue with the installation.
8. At the end of the installation process you will be prompted to reboot your PC; Dyalog APL will not be fully installed until the PC has been rebooted - it is recommended that you perform that reboot as soon as possible having installed Dyalog APL.
9. Double click on the new Dyalog APL shortcut on your desktop; enjoy Dyalog APL!

Additional information about installing Dyalog APL can be found here on the Dyalog Forums.

If you have problems typing APL characters, it is worth taking a look at the links at the bottom of the Fonts and Keyboard page on the Dyalog website at www.dyalog.com/apl-font-keyboard.htm.

We intend to issue updates to the conference edition from time to time. It is expected that to upgrade you will need to uninstall the conference edition, reboot your machine and install the latest version (which again requires a reboot).

If you have multiple versions of Dyalog APL installed on your PC, uninstalling any version may result in the APL fonts being uninstalled. Dyalog has placed a zip file containing the APL fonts here so that you can download and reinstall them.

There are more details in the FAQ section of the Dyalog Forums.

Installing the 2022 Conference Edition does not alter any file associations.
