Re: Spore Not Installing
Possible that the files were corrupted by a windows update.
The best way is to uninstall Spore and use your own windows tool "Disk Clean up".

If it complicated for you, use the tool CCleaner.

Important: You must to delete all old files, otherwise the game will revert to any files that are present.
After the whole process restart the computer
