Trouble installing PDF Creator

 I've used this program in the past, so I wanted to install it on my new
 machine. After downloading and running the setup file, when I go to run
 PDF Creator, it begins to install. The install process gets interrupted. A
 dialog box pops up saying "The feature you are trying to use is on a
 network resource that is unavailable." It continues to say, "Click OK to
 try again, or enter an alternate path to a folder containing the
 installation package 'softbar_installer.msi' in the box below." In the box
 below, "http://s3.amazonaws/softestbarwi/" is listed and I can not find
 the .msi file it asks for anywhere. What can I do?
