It might not be compatible for your type of computer or you might not have enough disc space.
No it doesn't.
No
If you are talking about installing a Sims 2 expansion to the Sims 1, it is impossible. You can only install the Sims 2 expansion packs into the Sims 2, not The Sims 1 or 3.
umm..i don't think you will need to install sims 2 before installign sims 3.
When installing it put it in another file than where you put The Sims 2. Then it'll work.
No, Sims Pets is only one disc.
I recon heaps of people :)
To install any sims 2 expansion packs you need to have the sims 2 installed. You cant just install sims 2 seasons for example, you need to have the sims 2 installed. It should say that on the box somewhere.
if you mean expansion packs yes
you can but it would not be wise it takes up extra space and the games will be separate so i would recommend that you uninstall the sims 2 before installing double deluxe
Try Un installing some The Sims 2 Games if you have any, or Get some RAM
Yes, try installing them to find out.
