simple installer with MUI2 - some questions

Hallo togehter, i'm new with NSIS
How to show a different text for titel and message in uninstaller page then in installer page
by using MUI or MUI2?
my current script




;Include Modern UI

!include "MUI2.nsh"

;--------------------------------

;General

 ;Name and file

  Name "Install Alice and change GTAIV version7 into version4"

  OutFile "Install-Alice.exe"

 ;Default installation folder

  InstallDir "C:\Program Files\Rockstar Games\Grand Theft Auto IV"

  ;Get installation folder from registry if available

  InstallDirRegKey HKCU "Grand Theft Auto IV" ""

 ;Request application privileges for Windows Vista

  RequestExecutionLevel user

Section "Uninstall"



Delete "$INSTDIR\testtesttest.txt" 



  Delete "$INSTDIR\Uninstall-Alice.exe"

1) I don't think the GTA4 regkeys will be in HKCU, because it installs to program files which requires admin access. Admin installers (should) write to HKLM. If it IS stored in HKCU, then it will be the admin's HKCU, so either way you need to elevate your installer. Use requestexecutionlevel admin and use the UserInfo plugin in .onInit to verify admin access.

2) What text do you want to change? The "Install Alice and change GTAIV version7 into version4" title? You can't do that (easily). You should instead use a better name, like "Alice GTAIV downgrader", and then put the longer "Install Alice and etc etc" as the component description.

3) In the future please use pastebin or an attachment to share large pieces of code.

Thanks for fast reply, i left the MUI and made it now with default nsis ui as slim as possible

my current script: alice install script / test

I want to allow the user to backup by uninstalling his custom files which he added
so i added a MessageBox MB_YESNO with following commands by true:
  CreateDirectory $DESKTOP\Alice

  CopyFiles $INSTDIR\Alice\*.* $DESKTOP\Alice
basicly it works but the Alice folder is unvisible on my Desktop
i can find it by using a file manager
and if the $INSTDIR\Alice folder contains more than 10 files it works as it should
is my system buggy or what's wrong?

off topic: how can i edit my submitted post?

edit
i found now the edit icon for this post but not for my previous post

oh, yes, F5 helped to show it

maybe i should backup the files in $DOCUMENTS

$docs would probably be a better choice, yeah. As for the caching issue... No idea, really. Try a second system and see if you can reproduce the problem.

that's an idea but when it happens on my system then it can also happen on another users system

$docs ? or $DOCS ? the compiler doesn't accept it and it isn't written in the user manual
is there a newer version than 2.46?

My next problem is to check by uninstalling if the Alice folder contains files
using wildcard IfFileExists $INSTDIR\Alice\*.* ask
the unistaller choose allways ask no matter if there are files or if the folder is empty
Section "uninstall"

IfFileExists $INSTDIR\Backup\GTAIV-V7.exe next

  MessageBox MB_OK "GTAIV-V7.exe was not found in Backup folder"

  Quit

next:

IfFileExists $INSTDIR\Alice\*.* ask

  Goto restore

ask:

MessageBox MB_YESNO "do you want to backup the Alice scripts?" IDYES true IDNO false

true:

  DetailPrint "Alice scripts are saved at My Documents\Alice"

  CreateDirectory "$DOCUMENTS\Alice"

  CopyFiles $INSTDIR\Alice\*.* $DOCUMENTS\Alice

  Goto restore

false:

  DetailPrint "All Alice scripts have been deleted"

restore:

  Rename $INSTDIR\Backup\GTAIV-V7.exe $INSTDIR\GTAIV.exe

  Delete "$INSTDIR\testtesttest.txt"

  Delete "$INSTDIR\uninstall-Alice.exe"

  RMDir /r /REBOOTOK "$INSTDIR\Alice"

  RMDir /r /REBOOTOK "$INSTDIR\Backup"

I was referring to the $DOCUMENTS variable.

That's because an empty subdirectory always contains . (current dir) and .. (parent dir). If the directory exists, dir\*.* will also exist.

shit, is there any method to check if the folder is empty?
is it possible to get the filesize of an folder?

I first found another method and want to discuss it just because of interest
It requires
!include "FileFunc.nsh"
	${GetSize} "$INSTDIR\Alice" "/S=0M" $0 $1 $2

	IfErrors 0 +3

	MessageBox MB_OK "error"

        Goto skip

	StrCmp $0 0 0 +3

	MessageBox MB_OK "Directory is NOT empty"

	Goto skip

	MessageBox MB_OK "Directory is empty"

	skip:
the code works as it should, if filesize $0 = 0 shows the MessageBox "Directory is empty"

then i thought i could check for the amount of available files with $1
StrCmp $1 0 0 +3
but that won't work correct
it shows allways the MessageBox "Directory is empty"

Am i totally wrong or didn't i understand the StrCmp?

String are really hard comparable 🙂
Some time ago there were some problems, but now they should be fixed.
Anyway, try to use "" for strings: StrCmp $1 "0" 0 +3

No, it also won't work, but anyway, i'll use the isEmptyDir function

As last i want to check if there are *.asi files in $INSTDIR and found the Locate_plugin
I studied the LocateTest.nsi and ripped the neccesary part for my current LocateAsifiles.nsi:
Name "Locate asi files"

OutFile LocateAsi.exe

!include "Locate.nsh"

Section

	GetTempFileName $1

	FileOpen $2 $1 w

	${locate::Open} "$PROGRAMFILES\Rockstar Games\Grand Theft Auto IV" "/F=1 /D=0 /M=*.asi /B=1" $R0

	StrCmp $R0 0 0 loop

	Quit

	loop:

	${locate::Find} $R0 $R1 $R2 $R3 $R4 $R5 $R6

	StrCmp $R1 '' close

	StrCmp $R4 '' 0 +3

	FileWrite $2 'DIR:"$R1" [Created: $R5] [$R6]$\r$\n'

	goto +2

	FileWrite $2 '$R1 $\r$\n'

	goto loop

	close:

	${locate::Close} $R0

	${locate::Unload}

	FileClose $2

	Exec '"notepad.exe" "$1"'

SectionEnd
my question now, what should do this line?
FileWrite $2 'DIR:"$R1" [Created: $R5] [$R6]$\r$\n'
it looks like it should list empty files with DIR: in the beginning of the line
but i couldn't imitate such a case
i added a folder with name mist.asi and an empty textfile and renamed it as test.asi
the folder was never listed and the empty file was allways listed without Dir: in the beginning

Your assumption is wrong! That example is simply writing to a temp file (GetTempFileName) and then opening it afterwards (Exec notepad.exe). If you want to find out what is going on, how about running it! Also never stick a loop in a Section. The progress bar will jump back and forth and this heavily degrades code performance. You should move the code to a function and call that.

I removed the FileWrite lines and added Rename $R1 $DOCUMENTS\AliceUninstfiles\$R3

Thank YOUUU all
I finished my script: Installing Alice and GTAIV-downgrade to GTAIV v5
Is it allowed to give here the link to download Alice-Installer.exe?
