Below are some common issues you might be having, and ways to solve them.

Openplanet compatibility

Openplanet is compatible with a variety of flavours of ManiaPlanet:

  • ManiaPlanet 4 is fully supported and can be downloaded here.
  • ManiaPlanet 3 is partly supported, but does not have a public build.
  • TrackMania Turbo is partly supported, but does not have a public build.

Pressing F3 does nothing in ManiaPlanet

This problem can have many causes, but a few common ones are:

  • Interfering third-party applications, such as anti-virus or firewall software.
  • Interfering overlays, such as MSI Afterburner, Overwolf, Geforce Experience, etc.
  • A corrupt installation of Openplanet.

You can try turning off some of these interfering programs on your computer before starting ManiaPlanet, which might solve the problem.

Another reason for this could be ManiaPlanet is blocking Openplanet temporarily. This can happen in circumstances where Openplanet has been proven to cause issues in ManiaPlanet such as instability. If this is the case, you can find status updates about it on Discord or the ManiaPlanet forums.

If none of the above seem to apply, you can start doing some more technical troubleshooting. First of all, check if there is a dinput8hook.log file in your ManiaPlanet installation directory. If it does, make sure there are no errors at the end of the file. A successful startup might look like this:

[22:00:00] Attaching DLL to: 'D:\Games\Maniaplanet\ManiaPlanet.exe'
[22:00:00] Module handle: 03D00000
[22:00:00] GetLastError: 183
[22:00:03] DirectInput8Create

From here you could look up the error or ask for more advice. If there is no logfile at all, check if there's a dinput8.dll file next to ManiaPlanet.exe. If there is not, your insallation is corrupt and you should try re-installing Openplanet. If there is, there's probably some anti-virus software blocking Openplanet from loading.

Next, you should check your main Openplanet logfile located at: C:\Users\<Your Username>\Openplanet4\Openplanet.log. Check if there are any obvious errors there, and ask for help if you can't figure it out.
