These are third party software so you either have to locate the source of
the download again or you might be successful with System Restore if that
option is enabled on your computer. If you go to Start button->Help and
Support->Pick a task->click on the System Restore link then follow the
onscreen instructions you can roll back to a date when the application was
installed. Do not go too far back in time though just try to get back to a
time and date immediately prior to the deletion. System Restore sometimes
works well and other times doesn't work at all so use it with discretion.
