InstallOptions and aborting the uninstaller

Hi all,

I need to do the following: when uninstalling, a custom page should be shown with 2 radio buttons:
a)- if one is selected I have to check that the user is admin and in case it is go further, if not abort the uninstaller with an error
b)- if the other radio-button is selected I have to run an .exe from the installation directory and abort right away the uninstaller (doesn't need to wait until the exe is finished)

What I did:
=============
- defined the page:
UninstPage custom un.UninstallModePage un.ValidateSelection ;Custom page
- reserve:
ReserveFile "UninstallMode.ini"
!insertmacro MUI_RESERVEFILE_INSTALLOPTIONS
- Extract InstallOptions INI files
!insertmacro MUI_INSTALLOPTIONS_EXTRACT "UninstallMode.ini"
- show it:
Function un.UninstallModePage ;UninstallModePage defined with Page command
!insertmacro MUI_INSTALLOPTIONS_DISPLAY "UninstallMode.ini"
FunctionEnd
- I added the un.ValidateSelection in order to do here the needed things for a) and b)
Function un.ValidateSelection ; when the user finished with the selection
; check if the selection is the second radio button and if yes for now do a MsgBox and abort the whole uninstaller
!insertmacro MUI_INSTALLOPTIONS_READ $INI_VALUE "UninstallMode.ini" "Field 2" "State"
StrCmp $INI_VALUE "1" 0 +3
MessageBox MB_OK "Here we should run another exe and then abort"
Abort ; abort somehow the whole uninstaller !!!

; check if the selection is the first radio button and if yes check that the current user is admin otherwise abort the whole uninstaller
!insertmacro MUI_INSTALLOPTIONS_READ $INI_VALUE "UninstallMode.ini" "Field 1" "State"
StrCmp $INI_VALUE "1" 0 done
ClearErrors
UserInfo::GetAccountType
Pop $1
StrCmp $1 "Admin" 0 +3
MessageBox MB_OK 'User is in the Administrators group'
Goto done
MessageBox MB_OK 'User is NOT in the Administrators group, so we should ABORT here somehow'
Abort ; abort somehow the whole uninstaller !!!
done:
FunctionEnd

Problems:
===========
- In both cases a) and b) I need to at some point completely abort the uninstaller. Those points are showed in un.ValidateSelection, check for "abort somehow the whole uninstaller !!!". How can I abort the whole uninstaller in those cases? For b) with no error message, and for a) with a MsgBox saying that the current user needs to be admin?
- In case of b) where and how should I run the exe just before aborting the whole uninstaller?

Sorry for the long post and thx in advance,

I think you want to use Quit instead of Abort. Example:

!insertmacro MUI_INSTALLOPTIONS_READ $INI_VALUE "UninstallMode.ini" "Field 2" "State"

StrCmp $INI_VALUE "1" 0 +3

 Exec app.exe

 Quit

For the case where you want to message the user that they are not an admin, use Quit immediately after your MessageBox.

Using Quit would kill the installer, without cleaning up anything in $PLUGINSDIR. The best choice here would be Return.

Ah, thanks for the clarification. I learn new things even when giving faulty advice to others!

dandaman32, that's not true. The $PLUGINSDIR clean-up has nothing to do with Quit. It's always done. There may a problem deleting InstallOptions.dll, if it's still in use, but it will be removed after reboot.

coco_vc, please use [ code ] or attach your scripts.

Interesting. According to the docs, Quit closes the installer almost immediately. In the ExperienceUI I call .onGUIend (which cleans stuff up from $PLUGINSDIR) and then use Quit.

Anyway Return would have just jumped to the next page, now that I think about it. If you're using the ExperienceUI you could use

StrCpy $XPUI_ABORTED 1

Return

to trigger the Abort page if that's enabled.

kichik, I will [ code ] next time. Sorry, wasn't aware of this.

The Quit did the trick. Thx.
So it's ok that I did all of these in the un.ValidateSelection?

Thx,
