Software Unable to Launch Orbiter 2024

[Henryv1598]

Whenever I try to launch Orbiter 2024 on my desktop PC, the launch screen comes up, but as soon as it does, it crashes to the desktop. This is a default install, no add-ons. Here's the long (all 4 lines of it):

**** Orbiter.log

Any ideas?

4 lines in the log isn't normal, it should be much longer. Make sure that the checksum of the archive you downloaded is ok.

Try copying zlib.dll from the root to /Modules/Server/

Ok, I was able to get it to launch using the Orbiter_ng.exe, but not the Orbiter.exe.

@N_Molson: I agree, 4 lines isn't normal. It appeared to be crashing way too early, though it DID flash the launchpad screen before crash. I tried running as an administrator and that made no difference. The archive looks fine, just, something fall down and go boom. Weird.

I have the exact same issue... NG version runs fine but Orbiter.exe crashes on startup. Same info in the log file too. Similar system specs as Henryv1598...

The Orbiter.exe (non NG) version, is using dx7 still. Most likely your hardware can't support dx7, or can't support it at the resolution you're trying to run it at.

The DX9 client is included in O2024, and is kind of the de facto standard now.

Hi, I have different problem : at start of Atlantis scenarios on launch pad the shuttle jumps and crashes very often. Joystick disabled ....
