Installing on Windows XP and Windows 2000

Hi all, could someone tell me how to install PostgreSQL on Windows XP and Windows 2000. I downloaded "PgSQL731wiin1a.exe" and ran the installlation but none of the applications worked. I read somewhere that if I moved the PostgreSQL directory frome "Programme" (german Windows) to the "Programes" directory it would work, which means that some things are hard-coded. Does some one have a sure method to install on these platforms?

Moving the Postgresql directory to a "Programes" directory helped only a little, I could at last start the commandshell, but connecting to the Database always failed, even with Pgadmin.

Thanks for your help in advance.
