I just downloaded the FIFA 12 Demo, but when I start the Autorun.exe I only get a play button, none for installation. If I click it, the FIFA 11 startup menu comes up.

If I start EASetup.exe, it says the game already is installed.

Any way to fix this?

For clarification: I have FIFA 11 installed and I am looking for a way to get the FIFA 12 Demo installed without uninstalling FIFA 11.

This seems to be a general issue with the demo, I found a german article on the web pointing out this issue as well. What I want to know is if there is a workaround to get the demo installed anyway.

What operating system do you use? Is it possible that Fifa 11 was installed on the system sometime before and was not uninstalled properly? –  Michael K Sep 13 '11 at 15:31
    
Fifa 11 is installed, Win 7 x64 –  atticae Sep 13 '11 at 15:33
    
Has fifa 12 been installed before? –  Michael K Sep 13 '11 at 15:35
    
Fifa 12 is not even released yet. ;) And no, the demo has not been installed before. –  atticae Sep 13 '11 at 15:37
    
I'm sorry, I don't know about sports games. You could try to uninstall fifa 11 and then install the demo, that might work. –  Michael K Sep 13 '11 at 15:39

there is no need to remove the whole registry key just add a suffix to it like

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products\1DC6AEF331AE7EC47AE47AA4A4A0B7C5backup

and the demo will install just fine. Afterwards you can remove it so you can properly uninstall fifa 11.

I now found a solution in this news article (german):

If you remove the following registry key

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products\1DC6AEF331AE7EC47AE47AA4A4A0B7C5

you are able to install the demo while Fifa 11 stays installed.

You should make a backup though, so that you still can uninstall Fifa 11 properly later.

I really appreciate your help. You just sort this out while I was really looking for a solution around internet. –  user12434 Sep 14 '11 at 1:04
    
Glad I could help. Wow, the views for this question really went through the roof. :D –  atticae Sep 14 '11 at 8:43
    
I tried to delete that registry key, and there was an "Error Deleting Values: Unable to delete all specified values." Therefore, I still have the problem with FIFA 12 not starting. –  user12444 Sep 14 '11 at 13:58
    
Maybe your account doesn't have the sufficient rights. Sounds like a problem for superuser though. –  atticae Sep 14 '11 at 14:45
