You don't happen to have a 32 bit x86 system do you?
I have Windows 7. So, it has the x86 capacity.
Does Second Earth require to run within the x86 directories? There doesn't seem to be any documentation on the proper way to install the game...unless I am mistaken and I simply missed it.
It's made for a 64 bit system, so x86_64. If your OS is 32bit (x86 and not x86_64) it will not run: it doesn't matter which directory it's on
You can check by right clicking on my computer and going to properties and looking for either 32bit or 64bit
I have a 64-bit system. The game launches and gets through the opening video, but then crashes after the video ends.
