How can I write the LanguageID into the Registry in Inno Setup?

I have 3 languages, so I write this:

Root: HKLM; Subkey: "SOFTWARE\Company\Office\Client"; ValueType: dword; ValueName: "LocaleID"; ValueData: "?"; Languages: en
Root: HKLM; Subkey: "SOFTWARE\Company\Office\Client"; ValueType: dword; ValueName: "LocaleID"; ValueData: "?"; Languages: ru
Root: HKLM; Subkey: "SOFTWARE\Company\Office4\Client"; ValueType: dword; ValueName: "LocaleID"; ValueData: "?"; Languages: ua

In the ValueData field I have to put the corresponding LanguageID ($0419 for Russian, $1058 for Ukrainian and $0409 for English, etc). I could put those numbers manually, but I wonder if there's a way to extract the LanguageID from its name or something.

You can use preprocessor to generate [Languages] and [Registry] entries at the same time. The preprocessor has ReadIni function, which you can use to read the LanguageID from the .isl files.

#define AddLanguage(Name, File) \
  "[Languages]" + NewLine + \
  "Name: " + Name + "; MessagesFile: ""compiler:" + File + """" + NewLine + \
  "[Registry]" + NewLine + \
  "Root: HKLM; Subkey: ""SOFTWARE\Company\Office\Client""; ValueType: dword; " + \
    "ValueName: ""LocaleID""; " + \
    "ValueData: " + ReadIni(CompilerPath + File, "LangOptions", "LanguageID") + "; " + \
    "Languages: " + Name + NewLine

#emit AddLanguage("en", "Default.isl")
#emit AddLanguage("ru", "Languages\Russian.isl")
#emit AddLanguage("uk", "Languages\Ukrainian.isl")

That will generate a code like this (lines wrapping and empty lines added for readability):

[Languages]
Name: en; MessagesFile: "compiler:Default.isl"

[Registry]
Root: HKLM; Subkey: "SOFTWARE\Company\Office\Client"; ValueType: dword; \
  ValueName: "LocaleID"; ValueData: $0409; Languages: en

[Languages]
Name: ru; MessagesFile: "compiler:Languages\Russian.isl"

[Registry]
Root: HKLM; Subkey: "SOFTWARE\Company\Office\Client"; ValueType: dword; \
  ValueName: "LocaleID"; ValueData: $0419; Languages: ru

[Languages]
Name: uk; MessagesFile: "compiler:Languages\Ukrainian.isl"

[Registry]
Root: HKLM; Subkey: "SOFTWARE\Company\Office\Client"; ValueType: dword; \
  ValueName: "LocaleID"; ValueData: $0422; Languages: uk

Add SaveToFile to the end of the script to see the generated code.
