expansions problems

hii.

i bought a guild wars stand alone expansion factions and started to build a warrior,
then i have notice that i dont have all the skills in factions, so i want to
buy the guild wars prophecies so i'll have all the skills.

my questions are:
1. where to install the prophecies, since i have the factions all ready installed?
2. should i delete factions to install prophecies?
3. after i'll install prophecies do i have to start all over again, buildin another char?
4. do the games bound together and create a hole game with bigger map or
what?

thanks in advance.

You don't need to install Proph. Just launch guild wars and click on the "Create account or install CD key". You will then be prompted to enter your CD key found in the game box. This will not effect any of your chars already created.

This is also not the forums for these kind of questions. You should go to the "Technical issues" forums or whatever nextime. We are helpful folk over here though; lucky for you.

Moved from GuildWiki forum.

Just install it to the default folder that it suggests. If, when you intalled Factions you haven't let everything stream to your Hard Drive from the login screen, then the content for Prophecies will just be "appended" to what you already have.
NO! No need
You can start from the very beginning, or you can take your Canthan chars over to Lion's Arch from Kaineng Centre.
Not quite. However, once you do the quest needed to get to another continent, you can use the boat icon on your Travel Map to freely switch between them.

DO NOT INSTALL, just log into game, ADD new key to your existing acct (this is easily done by going to manage/add keys, typing in your acct info and the key and hit add - The game will tell you what the key will add, and ask you if you are sure), and enjoy the new content. It doesn't add more to your map, it adds another map which you can access with either your current characters or with new ones created in Prophesies. The 2 maps are seperate and the only way to get between them is the boat (just like to battle isles) that you unlock with a quest either in Kaineng center/docks or Lion's Arch.

it does help indeed to install prophecies, cause i've noticed that u will need to download more files when u join an area at the first time when the other game not installed, so if ur having slow download rate when u join a map at the first time then it will be handy.
if u have not then it will not be needed cause u'll have the files in a short time
