Just make sure to do an antivirus scan before activating it. Or instead of adding rar, try ".zip" and see if you can try it that way.
Additionally, EA has announced an i Tunes-style "Spore Store" which will be built into the game itself, allowing for the digital distribution of future Spore expansion packs as well as Internet sales of Spore merchandise including t-shirts, posters, a collectible card game, and possibly custom figures created from 3D prints of submitted creature designs.
Spore Creature is the Nintendo DS version of spore, featuring different gameplay and overall design based more on story and adventure gameplay, the Nintendo DS version of Spore also featured a unique cartoony style.
Spore is being referred to as a "massively single-player" game, in which the procedurally generated content (animals, sentient species, planets, vehicles, civilizations, and so on) of each copy of the game are spread to every other copy of the game on the planet, as long as that person's computer is connected to the Internet.
Spore's gameplay is comprised of five individual phases, each based on a previously released franchise and genre.
If your game plays fine and you don't "need" the extra content, then see if you can keep playing like that, but if your game is buggy, then try updating.
But you may stop your game from playing, there is no surefire way to know if it will work or not.
Or, you can do as the others here are suggesting and see if you can find and download the patches from third party sources.
Since its a patch, I'd imagine it would come as an executable file and you should be able to double click it to start it up. Sometimes they have files compressed as RAR or ZIP and they left out the suffix, if you think its a compressed file (otherwise it shouldn't be unknown, the patch is a regular setup type EXE file) then if you have Win RAR, see if you can rename the file and don't change the name, just try to add in ".rar" at the end and see if you can open it with Win RAR.
I recently re-installed Spore after a long period of not playing it.
After re-downloading it through origin, it installs fine.
The player begins the game in the form of a microscopic organism that arrives on a planet via exogenesis or panspermia, deposited in the primordial oceans by a meteorite impact.
