how to Abort the Install on message box response

[valiot]

I've created a custom action to display a message box during the install. It's a YES/NO message box. I've assigned the response to a User Defined property. Now the big question:
If the user clicks the NO button, how do I abort the install?

Hi,

When you create a "Display message box" custom action you can set a property based on the button the user presses (in your case YES or NO). Then based on the value of the property you set, the installation of your application must continue or stop.

Unfortunately, Advanced Installer does not have this feature, but you can create a simple custom action which will run only if the NO button was pressed and that custom action stops the installation.

I attached to this post a simple VBScript custom action which you can run right under your "Display message box" custom action with the following settings:
- create a "Launch attached file" custom action and choose the VBScript I attached here
- in the "Function" text field write the function found in that VBScript (in this case ExitSetupFromVBS)
- in the "Condition" text field write the property you set with the return value of the "Display message box" custom action (i.e. MYPROP = "IDNO")

Let us know if this helped, otherwise give us more details about your scenario.

Best regards,

Doesn't seem to work.

Hi,

The only error I can see is that you written [BTN_PRESSED] instead of BTN_PRESSED in the "Action Data" text field of the "Display message box" custom action.

Let us know if this helped.

Hello,

I know this is an old post, but it matches my situation so I though I would continue it.

I am using 17.8 and set up a MessageBox custom action like so:

and then I am calling the same exit.vbs script if the CONTINUE_BTN_PRESSED = "IDNO"

ExitUninstallCustomAction.png (166.62 KiB) Viewed 6351 times

My problem is that the exit.vbs script runs successfully, but the uninstall continues. Is this script still usable in the latest versions?

Thanks,

Peter

Hello Peter,

From what I can see, your VBS custom action has the "Fail installation if custom action returns an error" option unchecked.

Please note that this is the whole ideea of this.

The VBScript custom action will return a value of 3:

Code: Select all

Const IDABORT = 3

A return code that is different than 0 will be interpreted by Windows Installer as failure.

Basically, your setup will try to uninstall --> the user will press "No" --> the VBScript custom action will be executed --> it will return 3 --> Windows Installer will interpret that as a failure --> the uninstall will not go any further --> the application is not uninstalled.

Hi Catalin,

Thank you for the explanation - that makes total sense now that you spelled it out. We want to force an error condition so it will quit the installer.

I checked the box for 'Fail installation if custom action returns an error' and it works great.

Cheers,

Peter

You are always welcome, Peter!

I am glad everything works as expected now and that my explanation helped.
