Uchtiv: I downloaded psychonauts installer and for now have this files:
setup_psychonauts_2.2.0.13.exe (32 MB)
setup_psychonauts_2.2.0.13-1.bin (3.9 GB)
setup_psychonauts_2.2.0.13-2.bin (90 MB)
Your installer says about: setup_psychonauts_2.1.0.12-1.bin
Really, try re-download all three files
LuxaPvP: Nope agine
Sorry, but would it be possible for you to answer the suggestions a bit more detailed and not just in two words so people who are trying to help you could really understand what you have tried out exactly?
This means:
Did you download the installer files mentuioed above? (2.2.0.13. - 3 files)
Did you figure out why these don't match the error message shown to you the first time?
Did you check the filesizes which are mentioned above? Are they identical?
Did you try to turn off the check before starting the install? What happens if you do this?
This might sound harsh, but I assure you it is not meant that way. Unfortunately only anwering "yes" or "no" will not get you far in getting your game to run which is the goal from you as well as from us. Providing as many details as possible regarding your problem and what you have tried usually is the fastest was to reach your goal.
