I tried to run the .sh file, and didn't work. Doing "./gog_broken_sword_5_the_serpent_s_curse_2.0.0.2.sh" in terminal gets me this:

Initial setup failed. Cannot continue.


Error: Couldn't run mojosetup


I don't know what to do now. I didn't have this problem installing things on 14.04.

There are many possible causes.

- Corrupted file (try redownloading it)
- Insufficient space in /tmp (check it and free space if needed)
- Permission problem in /tmp (the user must have rights to write and execute files in there)
- "Strange" characters in script file's path (put the sh file into a directory with a simple path such as "/home/username")

Redownloading seems to have fixed it.
