In recognition of player feedback regarding DRM and SecuROM on Spore, Maxis is offering a standalone download so that users can now "de-authorize" a computer if they would like to make that authorization available for another machine.
Machines can be de-authorized or re-authorized at any time. The total number of machines on which Spore can be authorized concurrently will continue to be five. To de-authorize a PC, download and launch Spore_deauth.zip and run the Spore De-Authentication Tool.exe file.
You can de-authorize at any time, even without uninstalling Spore, and free up that machine authorization. If you re-launch Spore on the same machine, the game will attempt to re-authorize. If you have not reached the machine limitation, the game will authorize and the machine will be re-authorized using up one of the five available machines.
This all came about because of feedback from the community, so keep that in mind! You can check out the patch on the
Official Site.
