[DUG] Vista help

[Ross Levis]

I didn't realize that about the common app data.  I thought this would 
be writable by all users.  So it's not possible now to allow multiple 
users to access the same data.  That's just great! (not).

I don't have Vista here but some users have managed to install and use 
my app fine on Vista provided they go to the program Files folder, 
right-click the installation folder, select Properties, Security 
Settings, and give the folder modify rights.  Then it works fine for any 
user.

So my new version will modify the security settings automatically during 
installation and there should not be any need for virtualization.

Cheers,
Ross.

Sorry Ross but my understanding is that this does break all the rules !

You cannot write data into program files\.  This includes your data sub
dir.  You should be using the users app data dir.  You are right and
wrong about common app data.  It is not difficult to use but it also
wont work under Vista.  Users have read access to common app data but
not right access.  So if your app needs to write settings it will have
to run as admin.

Your testing may not show this up as 'virtualization' can hide these
issues from you (sometimes??).

Have a look at

for what MS says (about 50 pages)
