Installer language

I made an installer that works with several languages, evrything works fine and when a user runs an installer the language selection screan appears.

But the problem is that if the same user runs the same setup on the same pc again the setup wont ask him to select a language and instead will use a language he selected the first time.

How can I make the installer to ask the user the language each time it runs ?

You have to delete the corresponding Registry key :-)

You have probably had to use some defines such as (the example is if you use the Modern User Interface plugin):
!define MUI_LANGDLL_REGISTRY_ROOT HKLM
!define MUI_LANGDLL_REGISTRY_KEY "Software\mysoftwarename"
!define MUI_LANGDLL_REGISTRY_VALUENAME "InstallerLanguage"

Which means the language selected by the user will be saved in the registry in HKLM\Software\mysoftwarename under the key name InstallerLanguage

Don't know though whether you can avoid the language to be saved in the first place by giving an empty registry path or using some other define?

Or you can use

!define MUI_LANGDLL_ALWAYSSHOW

Excelent !define MUI_LANGDLL_ALWAYSSHOW is exactly what I was looking for.

Thakns.

Hi

This work fine to me too, but when i run unistaller, this not "get" the language ive select when install.
I use this

;Uninstaller Functions
Function un.onInit
!insertmacro MUI_UNGETLANGUAGE
MessageBox MB_ICONQUESTION|MB_YESNO|MB_DEFBUTTON2 $(UN_QUESTION) IDYES +2
Abort
FunctionEnd

Did you check if the value is recorded in the registry with the MUI_LANGDLL_REGISTRY_ROOT, KEY and VALUENAME you gave?

If it's correct, maybe try with calling the message box after stepping out of function un.onInit?

The MUI_LANGDLL_REGISTRY_ROOT, KEY and VALUENAME are OK

The stranger is that only happens in messagebox of onInit since in the one of onUninstSuccess works fine with the language of the installation

Function un.onUninstSuccess
HideWindow
MessageBox MB_ICONINFORMATION|MB_OK $(UN_CONFIRMATION)
FunctionEnd

Any idea?
TIA

The language selection doesn't take effect until after .onInit. You can use .onGUIInit to display multilingual messages with ease, or you could use a switch on $LANGUAGE.

Thanks Kichik

And in this part of code how i could use $LANGUAGE??

;Uninstaller Functions
Function un.onInit
!insertmacro MUI_UNGETLANGUAGE
MessageBox MB_ICONQUESTION|MB_YESNO|MB_DEFBUTTON2 $(UN_QUESTION) IDYES +2
Abort
FunctionEnd

Function un.onUninstSuccess
HideWindow
MessageBox MB_ICONINFORMATION|MB_OK $(UN_CONFIRMATION)
FunctionEnd

If you want to use language strings, use them in un.onGUIInit. If you really must use it in un.onInit, use a switch.

!include LogicLib.nsh

#...

${Switch} $LANGUAGE

  ${Case} ${LANG_ENGLISH}

    MessageBox MB_OK english

    ${Break}

  ${Case} ${LANG_FRENCH}

    MessageBox MB_OK french

    ${Break}

${EndSwitch}

Thanks Kichik, but i still vae problems with uninstaller
This is my part of code with your help

;Uninstaller Functions
Function un.onInit
!insertmacro MUI_UNGETLANGUAGE
!include LogicLib.nsh
${Switch} $LANGUAGE
${Case} ${LANG_ENGLISH}
MessageBox MB_ICONQUESTION|MB_YESNO|MB_DEFBUTTON2 "Are you sure you wish to uninstall $(^Name) with all componentes?" IDYES +2
Abort
${Break}
${Case} ${LANG_SPANISH}
MessageBox MB_ICONQUESTION|MB_YESNO|MB_DEFBUTTON2 "¿Está completamente seguro que desea desinstalar $(^Name) junto con todos sus componentes?" IDYES +2
Abort
${Break}
${Case} ${LANG_PORTUGUESEBR}
MessageBox MB_ICONQUESTION|MB_YESNO|MB_DEFBUTTON2 "¿Voce está completamente seguro que desea desinstalar $(^Name) junto con tudos sua componentes?" IDYES +2
Abort
${Break}
${EndSwitch}
FunctionEnd


At this time the messagebox shows ok and in the install language, but the title of the unistall window still in Spanish, but not the title of unistall confirmation.
If you wish ive attach some images.

TIA

In that case, you can set Caption to a variable and change that variable in that Switch according to the selected language. Or simply put that message box in un.onGUIInit.

Thanks kichik, but if ive try that the compiler says
Error : Function named "un.onGUIInit" already exists.

In other way how can I " set Caption to a variable and change that variable in that Switch according to the selected language", could you help me with some lines in my above code?

TIA

You need to tell the MUI you want to use it with MUI_CUSTOMFUNCTION_UNGUIINIT.

Ok and whatsup with

how can I " set Caption to a variable and change that variable in that Switch according to the selected language", could you help me with some lines in my above code?

Thanks a lot

You shouldn't use that. Use un.onGUIInit, it's by far the best solution. But if you insist...

Var caption

Caption $CAPTION

Function un.onInit

# if english...

StrCpy $caption "some caption"

MessageBox MB_OK "some message"

# if hebrew...

StrCpy $caption "koteret"

MessageBox MB_OK "hoda'a"

FunctionEnd

Hi kichik, sorry for insist but just Im beginning with NSIS and are many things that exceed to me, thanks to answer.

Kindly

Hello everyone. Kichik is right. This is very interesting. Try this way it works. After adding conditionals that they want wherever they want.

Name "ChangeCaption"

OutFile "ChangeCaption.exe"



Var CAPTION

Caption $CAPTION



Function .OnInit
StrCpy $CAPTION "MyNewCaption"

MessageBox MB_OK "You NOT see the caption here"
FunctionEnd



Section SectionOne
MessageBox MB_OK "You NOW see the caption here"
SectionEnd

Kichik: you are the master, add this to the Code Example.
