How to remove read-only attributes on folders in C:\ProgramData with Windows 7

I'm trying to set up a site-wide deployment for an application that has a tree of data users need to read and write under C:\ProgramData\<application>

The folder C:\ProgramData\<application> and its subfolders show the "I" attribute when viewing attributes with the "attrib" command. The "R" attribute is not set. However, folder properties in the Windows Explorer show the "Read-only (Only applies to files in folder)" attribute box is selected.

I can try to unset the read-only attribute using the Windows Explorer properties menu; it will ask if I want to "Apply changes to this folder, subfolders and files"...and that dialog box will go away after pressing "OK". Closing and reopening the properties box still shows the read-only attribute checked.

I tried to use "attrib +r C:\ProgramData\<application> /S /D" to add read-only attributes to the directory tree; "attrib" shows the read-only property at this point. I then attempted to remove the read-only attribute with "attrib -r C:\ProgramData\<application> /S /D". "attrib" shows the read-only property gone at that point, but the Windows Explorer properties window shows the read-only attribute still checked.

Security ACLs for C:\ProgramData\<application> give group "Users" read and write permissions, and C:\ProgramData\<application>\<version_num> has full control access granted to "Everyone".

I did find http://support.microsoft.com/kb/326549 addressed this issue somewhat, but I did not find any suggestions there I didn't already try (and document above).

Any suggestions for how to remove this read-only folder attribute from folders in C:\ProgramData on Windows 7 systems?
