I keep getting a "Failed to load mono" notification and can't open the game, any way to fix this?

That error is specifically the Unity engine failing to start, because it cannot find the mono.dll that is inside the Mono directory.

One possibility is that you could have the exe file located in a different directory from the associated Mono directory. Always make sure to copy all of the files from the archive to the same directory on your machine.

Alternatively it could be something strange in the path to where the game is stored. For reference:

If you had it installed via the itch client, then I'll have to do more investigating.


Sorry for the late reply. I've downloaded the game off of, and have everything in one folder: Mono(folder), DinosauriaAlpha2Win_Data(folder), the Dinosauria application to run the game, the Unity crash handler,  and the unity player.  Is there something I need to move/change? That's how it came downloaded.

It is supposed to just work so long as all of the files are in the same folder an a computer, and that computer meets the minimum requirements to run Unity:

Alternatively you can install the client, and download/play Dinosauria with the client.

I am not familiar enough with the error to remotely troubleshoot.

whenever i try to play it says "put it next to the excutable." can you help?

It is the executable that is giving an error message stating: "put it next to the excutable.".

It might be that you are trying to run it from the archive, which it cannot; here is a video I found demonstrating this:


but do you need winrar
