    </Fragment>
  <Fragment>
     <!-- This section is related to custom action-->
    <Binary Id="CABinary" SourceFile=".\CustomActionsFolder\CustomActions.CA.dll" />
    <CustomAction Id="UserNameAndPasswordCheck" BinaryKey="CABinary"  DllEntry="CheckUserNameAndPassword" Execute="immediate"/>
  </Fragment>
</Wix>

CheckUserNameAndPassword is the method name.

My custom action is not executing at all. I have a message box in my custom action; It is not at all showing and also I am logging the action start and end. In log file also it is not showing anything related to my custom action.

What was my mistake?

Answer 1

Did you reference it in your InstallExecuteSequence?

<Binary Id="CABinary" SourceFile=".\CustomActionsFolder\CustomActions.CA.dll" />
<CustomAction Id="UserNameAndPasswordCheck" BinaryKey="CABinary"  DllEntry="CheckUserNameAndPassword" Execute="immediate"/>

<InstallExecuteSequence>
    <Custom Action="UserNameAndPasswordCheck" After="InstallFinalize"/>
</InstallExecuteSequence>

Otherwise it will indeed not be run. Hope this helps
