Error code 1004

The same thing happens to me and i have heard of many ways to fix it try this, i got it off a steam forum from this guy named McGunns 

I checked the Spore forums, because I too were having the exact same errors and this is what I found.
It is due to 64 bit Window 7 registry deleting the SPORE entries automatically after each installation and patching. 

HOW TO FIX SPORE for 64 bit Windows 7 
1. Open C:\Windows\regedit as administrator 

2. Find 
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432node\Electronic Arts\SPORE 

3. Add the following as string value if they are not there 
AppDir = SPORE 
DataDir = C:\Program Files (x86)\Electronic Arts\SPORE\Data\ 
InstallLoc = C:\Program Files (x86)\Electronic Arts\SPORE 
PlayerDir = My Spore Creations 

4. Add the following as 32bit DWORD value 
ReIndexYesOrNo = 0 
InstallCompleted = 1 

5. Open Spore and have fun 

Note: change the blue text to your installation directory, the one shown is the default directory

>blue text was the c:\ files next to DataDir and InstallLoc
I tried looking for the exact place but I couldn't find the files to change. 

Maybe you will have more luck

But I fixed it by watching this video and downloading the patcher it showed in the video

i pretty much did the same thing as oats william, but a bit differently

works on windows 10

step one- go to regedit

step 2 do whatever oats said to do untill you are at the correct directory 

step 3 delete all spore stuff you see. if it says spore, delete it.

step 4- uninstall spore and all other spore related applications you have installed (make sure in appdata you delete ONLY SPORE RELATED STUFF. it could destroy some other games you may own if you delete anything else.)

step 5- reinstall spore and all of its dlcs or expansions (if you have any)

step 6- launch spore.

it should work, if not, or you dont trust yourself, contact official help from EA.
