The Open Cave

Hello, I have installed TOC today on my computer and when I wanted to do it on my partner's computer, following the same steps all went fine until the last moment, the game didn't want to start, I got the message that there is not enough space on hard drive and that is not true. I checked and there is 393 GB free space left ! We tried rebooting the computer but nothing changed and we can't start the game Please help.

Did you try running the game as an administrator? That could be an issue if you have the game in C:\Program Files.
