Installer - change default install location

[mihaijulien]

Hello,

I need to automate the install process of an application. Everything works fine when using the default configuration. But there's a problem when changing the default install location.

I have the following code:

expandcollapse popup

#requireadmin

#include <FileConstants.au3>
#include <WinApi.au3>

Opt("WinTitleMatchMode",2)

Global $defaultLocation = "C:\Program Files\MyApp"
Global $alternateLocation = "D:\MyApp"

InstallG2()

Func InstallG2()

   Local $hWnd = "Install Wizard"
   Local $dir = DirCreate($alternateLocation) ;create alternate location folder

   ShellExecute("win-installer-5.6.0.msi","",@ScriptDir & "\c2")

   While Not ControlCommand($hWnd,"","[Text:&Next >]", "IsEnabled",'')
      Sleep(500)
   WEnd

;if the app is already installed, close the install wizard
   If ControlGetText($hWnd,"","[Text:Remove Installation]") Then
      WinClose($hWnd)
      Return
   Else

      ControlClick($hWnd,"","[CLASS:Button; INSTANCE:1]") ;first Next ;1572
      Local $counter = 0
      For $counter = 0 to 1
         Send("{TAB}")
         Sleep(100)
      Next
      Send("{UP}") ;accept the terms in the License Agreement ;57
      Sleep(100)
      ControlClick($hWnd,"","[CLASS:Button; INSTANCE:1]") ; Next ;1572
      Sleep(500)
      ControlClick($hWnd,"","[CLASS:Button; INSTANCE:5]") ; uncheck start
      Sleep(500)

      ;install in a different location
      _selectEdit($hWnd)
      ControlSetText($hWnd,$defaultLocation,"[CLASS:Edit; INSTANCE:1]", $alternateLocation)
      Sleep(1000)

      ControlClick($hWnd,"","[CLASS:Button; INSTANCE:1]") ; Next ;1572
      If ControlGetText("Error","","[CLASS:Button; INSTANCE:1]") Then
         Exit
      EndIf

      ; wait the install successful UI
      While 1
         $var = ControlGetText($hWnd, "", "[Text:&Finish]")

         If $var == "&Finish" Then

         ControlClick($hWnd,"","[CLASS:Button; INSTANCE:1]") ;Finish

            ExitLoop
         EndIf
         Sleep(1000)
      WEnd

   EndIf

EndFunc

; select the edit text box when changing the install location
Func _selectEdit($hWnd)
   $hWnd = _WinAPI_GetFocus()
   $class = _WinAPI_GetClassName($hWnd)
   If $class = 'Edit' Then _GUICtrlEdit_SetSel($hWnd, 0, -1)
EndFunc

The above code doesn't work, when the installing process reaches the step for choosing the install location, it throws an error "Path already exists". If I comment this line:

;Local $dir = DirCreate($alternateLocation)

then the app installs in the default location, even though I change the install location.

 

Any ideas what could be wrong or any workaround?

So, I am stopping the script after it sends the alternate location to the edit box and from that point I continue the installation manually.

expandcollapse popup

#requireadmin

#include <FileConstants.au3>
#include <WinApi.au3>

Opt("WinTitleMatchMode",2)

Global $defaultLocation = "C:\Program Files\MyApp"
Global $alternateLocation = "D:\MyApp"

InstallG2()

Func InstallG2()

   Local $hWnd = "Install Wizard"
   Local $dir = DirCreate($alternateLocation) ;create alternate location folder

   ShellExecute("win-installer-5.6.0.msi","",@ScriptDir & "\c2")

   While Not ControlCommand($hWnd,"","[Text:&Next >]", "IsEnabled",'')
      Sleep(500)
   WEnd

;if the app is already installed, close the install wizard
   If ControlGetText($hWnd,"","[Text:Remove Installation]") Then
      WinClose($hWnd)
      Return
   Else

      ControlClick($hWnd,"","[CLASS:Button; INSTANCE:1]") ;first Next ;1572
      Local $counter = 0
      For $counter = 0 to 1
         Send("{TAB}")
         Sleep(100)
      Next
      Send("{UP}") ;accept the terms in the License Agreement ;57
      Sleep(100)
      ControlClick($hWnd,"","[CLASS:Button; INSTANCE:1]") ; Next ;1572
      Sleep(500)
      ControlClick($hWnd,"","[CLASS:Button; INSTANCE:5]") ; uncheck start
      Sleep(500)

      ;install in a different location
      _selectEdit($hWnd)
      ControlSetText($hWnd,$defaultLocation,"[CLASS:Edit; INSTANCE:1]", $alternateLocation)
      Sleep(100000000) ; <----------- I stop the script here
 EndFunc

The result is the same, the app install in the default location at C:\Program Files\MyApp. 

That's pretty strange.

Ok, so I found a workaround. Instead of: 

ControlSetText($hWnd,$defaultLocation,"[CLASS:Edit; INSTANCE:1]", $alternateLocation)

I used: 

Send("D:\MyApp")

Why not use the msi properties for example:

Global $alternateLocation = "D:\MyApp"
RunWait('MsiExec.exe /i "' & @ScriptDir & '\c2\win-installer-5.6.0.msi" /QB InstallDir="' & $alternateLocation & '" /NoRestart')
