Add-Remove Uninstall and msiexec /x not working accordingly for WiX-based installers

I’m facing this strange behavior for some of my WiX-based installers. After installation, if I try to remove via Add Remove Program (Programs and Features in Windows 7) using Right Click Menu and select Uninstall (This default BTW), it only shows a progress dialog which quits immediately and program never uninstalls and stays intact.

The Same behavior is there upon using

msiexec /x {ProductCode}

(or Product.msi)

However, using Right Click Menu, select Change and then from Maintenance Dialog Box, select Remove, uninstalls it perfectly.

Here is the code for InstallUISequence and InstallExecuteSequence:

<InstallUISequence>
    <Custom Before="CostFinalize" Action="CheckPreReqs" />
    <Show Dialog="MaintenanceWelcomeDlg" 
          Overridable="yes"

How do I fix this problem?

Chances are that you are attempting to do "stuff" during the InstallUISequence (which doesn't display from ARP or msiexec /x) and you are (incorrectly) requiring a User Interface and performing steps here, as opposed to performing them during the InstallExecuteSequence

If you inspect the two sequences using Orca, you should be able to identify the problematic actions.
