Hi Arnór,
the small Languages entry (on the left, which is read-only) shows the
default language ID (if any) from the specific .exe, .dll, .ocx, etc. file.
Let us assume, you would like to install the file on English (1033) and
Italian (1040) Windows machines only (primary language identifier on these
target machines is set to 1033 or 1040). Then you type the following
decimal values into the longer entry (on the right): 1033,1040
As a result, the file will *not* be installed on, say, a German (1031) or
Swedish (1053) Windows machine. It will only install on English (1033) and
Italian (1040) machines.
I think it's always the same value on your machine because your default
language in the compiled version resource is set to English (US) = 1033. See
attached screenshot. This is from an .exe with Language ID set to 0x0807
(= 2055 which is "Swiss German").
