see attached files. place both of them on desktop and open run simio file. It does not work properly because path 3's none of the add-on processes work (i.e., I set process 2 for 4 add-ons of Path 3 but it does not write to excel. In order to make it work properly I defined an add-on process to first test's output note (set process 2 for exited add-on of first test) and it works. This should be a bug and must be fixed. Pls report this to support team.
