Hi,
As explained in our tutorial this type of custom action creates two DLL files, the one you need to use is the one with the name ending with "
.CA", as you can see in the attached picture, under "Source Path" field.
Also, in the "Function" field you need to specify the name of your custom action from the DLL that should be called. You can have multiple custom actions in a DLL so the MSI requires for your specify it.
Even if there is a single custom action in it you still need to specify the function name.
Please analyze carefully
our tutorial if you will also need to debug your custom action.
Best regards,
Bogdan
