First check that your system meets the minimum requirements...ie. you have at least 512mb of ram, CPU of at least 2Ghz Pentium4 or equivalent(with off-board video), and your hard drive has >4GB of free space.....can view full list at:

Is SPORE on a duel layer dvd? If your drive is on the older side, you might try a newer one or you can try the following:
--take out an empty flash drive with
--go to a computer that will read the disk...if you have another computer or u can use someone elses
--put the disk in their computer and if the computer is able to read the disk, then put your flash drive in the computer and copy the disk onto your flash drive...
-y-ou can now try to install the program from your flash drive instead of using the disk...
NOTE: Trying this method wont cause any damage, but if the disk is encripted or if the install software is set to check for the disk during installation, then this may not work, but is worth trying since because a) even if it doesn't work, no harm is done, and b) you wont need to replace your disk drive if it does work.
