That happened to me before.
Your Notes9.0.1 installer that you initially used is wrong one. This is weird thing, but true. See this one - > https://www-01.ibm.com/support/docview.wss?uid=swg21659925
But there is a workaround here. When you installed your FP, the installer extracts files to e.g., C:¥temp¥IBM¥NotesFP¥ you specify, then go to deploy¥hotfix folder under the folder you gave.
You will find fix.ini and ForVersion=20131022.0932 in the file.
You should change the value 20131022.0932 to your "20131015.0605".
Then you launch the installer .exe you extracted before.
It should work.
Otherwise, re-download new installer.
