I came across a problem when trying to delete a file on updating: if the file to delete is not present applife does a rollback ending with the same version that applife tryed to update in the first place. ¿How can delete only if is present in the folder?¿should i have to do a custom action? if yes ¿could you guide me in how to accomplish this?

thanks

regards

here's the log:

As you see the file is in use by Internet Explorer, that's why it rolled back everything. Now, can you tell me a way i can enable uplife to not rollback if this happens?
