Where to put common writable application files?

In my application I have some setting-files, which needs read/write permission and should be accessable by all users.

So far I found in the net is, that microsoft gives you some special folders in Win Vista/7, but none of them fulfills my needs:

1) CSIDL_COMMON_APPDATA => C:\ProgramData, has no write permission

2) CSIDL_APPDATA => is user specifc

3) CSIDL_LOCAL_APPDATA => is user specific

How can I access such folder, which contains APP DATA, is accessable by all users and has read/write permissio开发者_StackOverflown?

on a system wide installation, you have to write them to CSIDL_COMMON_APPDATA. but you have also to set the permissions within your setup.

don't give rights to "everybody" - "authenticated" is better

if you are using windows installer, then you have to take care of users and system installations. if it is a user installation, you have to write to the CSIDL_APPDATA or CSIDL_LOCAL_APPDATA (depending of roaming or not roaming data).

If you understand german take a look in the entwickler magazin 3.2011. there will be a article "Einstellungssache", which is on topic.
