So I launch up the launcher and when I click "Launch Starbound" inside the launcher this pops up: Clicking "OK" leads to this: Clicking "OK" here just closes it and there are no further errors, but the game does not launch. Reading the actual error I can tell you this, the game is not looking on the correct harddrive. My game is installed to the C:/ Drive, not the E:/ drive. The Steamworks folder does not even exist on my E:/ drive. The game launcher window stays open, and when closed steam believes that I am still in the game. Looking in my task manager I find this: The largest processes on my entire computer. I must end them from the processes window in order to launch the launcher again, but as such there is not much point due to the previous errors. I am running on Windows 7 64 bit OS, my account has full privileges. Also running the game .exe directly from the folder that it is actually in still gets me this error even though it is on the C:/ drive. EDIT: I tried everything i've come across to workaround the problem and have finally found a solution. The problem is not with running as administrator, since that doesnt work at all, the solution I had to do was this Solution: Since my user account is the only one on the PC I am using, since I am the owner of said PC, I have administrative rights over everything, I have everything set to run as administrator by default. So setting things to run as admin did not help. I had tried every workaround but one, which was an odd one at that, which is to NOT run the game as administrator. In order for me to do this I had to create an entire new user on my PC, log out of my administrator user, and log into this new user I had created as a standard user, then I launch up steam and run the game and it works. This is a bloody awful workaround, as none of my stuff/settings/ etc is on this account. So chucklefish, if you are reading this, please fix this issue ASAP. There is no reason the game should not work when run as an administrator. There is no reason I should have to create an entire new user on my PC with less privileges in order to launch something.
