Quote - when I launch it always asks me to locate something

This has absolutely nothing to do with 'Preferred State'. It is caused by files not being in the correct location. Poser files such as pz3 (scene), or cr2 (character), etc, call on other files, and if the files they are calling are not in the expected location in your runtime you will be asked to locate them.

This problem can come about in various ways.

1). If you did not install content correctly.
2). If you moved content after installing it.
3). A faulty installation package (eg zip) installed stuff to the wrong place.
4). A faulty path in an installed file.
