Game installed fine but would not run by default in Ubuntu.

Errors:
Configuration Script Failed [2000]
Could not find a needed package The data directory is missing or corrupt [1004]

To fix:

Edit the "system.reg" file:
example location: 
/home/your_username/.steam/steam/steamapps/compatdata/17390/pfx/system.reg

Add the following lines to the system.reg file (replace "your_username" with your actual username)

Note: Ensure that the directory locations for "datadir" and "installloc" are where your Spore installation was installed. If it isn't, change the texts below to point to the full path of your Spore installation.

TLDR: Installed fine but would not run by default in Ubuntu. Had to edit the system.reg file to add an entry for the game for it to run. Works fine after that.
