Windows 10: adding Dyalog Unicode IME as an input method

Postby Vince|Dyalog on Fri Sep 11, 2015 10:22 am

On Windows 10, when I go to Settings | Language and press the Options button for my language and choose "Add a Keyboard", Dyalog APL IME is greyed out and its description is "Input method editor (desktop only)".

Here are steps to be able to type APL characters using our Unicode IME:

1) Start button->Settings

In the "Find a setting" edit field, type Advanced keyboard settings

Click on the icon with that text on it

Under Switching input methods:
Tick the “Let me set a different input method for each app window”

Tick the "Use the desktop language bar when it's available". This option will show the orange D icon when our Dyalog Unicode IME is active.

Close this dialog with the X button in the top right.

2) In this registry location:
HKEY_CURRENT_USER\Keyboard Layout\Preload

I would expect to see some string values with names like 2 or 3, and the value is something like e0990409

If there isn't one, you can add one.

e.g., If numbers 1 and 2 are used, add a new String value Named 3, which is the next in the sequence and give it the value:


Restart your computer and you should be able to type APL using our Unicode IME.

For example, press Ctrl and the I key to get ⍳, and Ctrl and the R key to get ⍴.

For en-GB the equivalent string is e0990809.
French: e099040c
Swedish: e099041d

The value string in that key refers to this related registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layouts\e0990409

On Windows 10 Enterprise basic users do not have access to Advanced Settings. So they can not tick the "Let me set a different input method for each app window". If person with admin permissions will set that input methdod setting for my computer, it will not anyway work with my user pofile. Does anyone know remedy for this problem? Thanks in advance!
