Problem: TrainSimWorld 5 API does not start with the parameter -HTTPAPI. Steps Taken (No success): Antivirus/Firewall: Added full folder exclusions for the TSW5 directory in Windows Defender. Network Reset: Performed a Full Restart (Shift+Restart) to clear orphaned PIDs and reset Winsock. Environment Variables: Added OPENSSL_ia32cap with value ~0x200000200000000 to address 13th Gen Intel OpenSSL bug. Permissions: Verified Documents folder is not "Read-Only." Attempted to run the Shipping .exe directly as Administrator. Files/Cache: Verified game integrity on Steam. Attempted to clear webcache and PersistentDownloadDir (Note: Saved folder does not exist as the game fails before first-run initialization). Direct Launch: Launching from the Binaries/Win64 folder results in no error message; the process simply terminates instantly. Reinstall: I uninstalled the game with revo Uninstaller and installed it again Does anyone have an idea what the problem might be? Thanks in advance for the help!!
@lefterisbsr#9747 In your first sentence, there is a full stop after -HTTPAPI But you entered -HTTPAPI without this full stop in Steam, right? Normally, that is the only thing you need to enter in Steam for TSW under Properties. And what is Revo Uninstaller? In Steam, you uninstall TSW via Steam and then reinstall it via Steam. Did you also add mods to TSW5? If so, I would remove the mods and then restart TSW5.
