Steam Library must be on a filesystem mounted with execute permissions 1

Question

I have installed Ubuntu 14.04(Dual Boot with Win 8.1) lts with about 12-13gb disk space.
I installed Steam and tried to install DOTA 2 which requires about 10gb of space ,but I have only 6 gb left.
I tried installing it on a different partition(windows) however it refuses to select a directory in any of the windows partition stating the above error:
Steam Library must be on a filesystem mounted with execute permissions 1

Answer 1

Add an entry in the fstab file at: /etc/fstab for your device. With "exec" option, for example:

UUID=6C046CDF046CADB0 /media/SAMSUNG ntfs rw,user,auto,exec    0    0

Answer 2

i found a very easy answer for this problem, just type this in the terminal udisks --mount /dev/sda2 --mount-options umask=022 (mounts with exec) steam will accept the windows partition and start downloading/installing your game.

Answer 3

There is a workaround.

• In windows create the Steam Library on the Windows drive
• In linux create a new Steam Library on you linux partition.
• Close Steam and remove the files inside the Steam Library folder.
• Link your newly created Steam Library on linux to your windows Steam Library with:
  ln -s /path/to/windows/Steam_Library /path/to/linux/Steam_Library
