I have made a custom install, and the program isn't in the default repertory. I think it is the source of the impossibility to update to 0.77 .
Edit: I tried some "dirty" tricks to update, but without any results. First try, move my Stardock Games repertory to the Programme repertory: no success. After this, moved the same repertory to program files(x86), no more success. I can't update my game and the download section only propose the 0.75 version and the patch 0.77. Making a direct download of the 0.77 isn't possible?
Thanks for any return about this.
