Hi Blair, Thanks for your reply. Lots of important info here. For ARP, I know what you mean. So how about uninstall from a shortcut(which is created when installing) in the [Start]->[All Programs]? Is it also impossible to add that dialog box? If not, I'll try to explain to our team. Also you said "Other posts address how to insert a dialog into a WiX UI sequence." - does it mean we could add a dialog box in uninstallation? Thanks again.

You can suppress the "Remove" button (ARPNOREMOVE property) which will create a "Change/Remove" button in its place where you can show a dialog to ask for permission to remove the user data. During major upgrade, the removal is always performed disallowing modal dialogs (IIRC). All dialogs are to be shown during the InstallUISequence. Use conditions to select your "starting" dialog in your "wizard" or other UX in that sequence. Look at the Repair/Change/Remove screen of the "maintanence" dialog sequence to see where the "Remove" option takes you and insert your new dialog there.

Subject: Re: [WiX-users] How to add a dialog box when uninstall Help please! I need to finish this task by tomorrow. If I can't make it, I might be fired. My job as a Wix developer may be ended. Please help: I just need to add a dialog box when install to ask if the end user wants to remove the settings data in user's AppData folder. If yes, I then will use my C++ program to remove the folder. This dialog shouldn't show up when doing major upgrade - we'll need to keep the setting anyways in this case. I know I need to define a dialog box, showing it, and create custom action, but how to do it? Please give some code example, or hint, or link. Anthing is appreciated. I'm looking for your help. ________________________________ From: little.forest <[email protected]> To: General discussion for Windows Installer XML toolset. <[email protected]> Sent: Wednesday, August 26, 2009 10:12:07 AM Subject: Re: [WiX-users] How to add a dialog box when uninstall Thanks Sebastian. Is there any source code example that shows how to do it? Also, how can we make sure this dialog box only pops up when the end user doing manual uninstallation? When the end user doing major upgrade to a newer version, this dialog box shouldn't popup because the end user will keep using the new version of the software - therefore the settings are still needed anyways. Is it possible to ensure this point? Thanks again. ________________________________ From: Sebastian Brand (Instyler Software) <[email protected]> To: General discussion for Windows Installer XML toolset. <[email protected]> Sent: Wednesday, August 26, 2009 12:18:29 AM Subject: Re: [WiX-users] How to add a dialog box when uninstall Hello, Windows Installer executes uninstall in Silent mode (no UI) mode only. To show a dialog, you'll have to create a custom action to show a dialog, then schedule that during uninstall.

How to add a dialog box when uninstall? We'd like to ask the end user if they want to delete their settings files in AppData\Company\Product folder. If the answer is Yes, then we'll need to delete that folder. And we only want this dialog box showing up when manually uninstall by either click the uninstall shortcut or from ARP in control panel. We do NOT want this dialog showing up when the user doing a major upgrade(installing a higher version, the old version is uninstalled). Thanks. /Brian __________________________________________________________________ Be smarter than spam. See how smart SpamGuard is at giving junk email the boot with the All-new Yahoo! Mail.
