It looks like an error caused by attempting to run the game directly out of the zip file it's in. Try to fully extract the zip file into a folder on your computer, then run CosmobreederYiffai.exe from there.
Open the zip file in WinRAR, then click the "Extract To" button. Another window named "Extraction Path and Options" will pop up. Select the folder that you want to extract the game to, then click the OK button.
Then navigate to the folder that you extracted the game to and run the game by double clicking CosmobreederYiffai.exe.
