Yay!!! They fixed this for VS2005. You can now do this. From the
Documentation
http://msdn2.microsoft.com/en-us/library/5f981xa1.aspx
================================================== =========
"The InstallAllUsers property for a deployment project determines
whether an application is installed for all users of a computer or only
for the user performing the installation. The InstallAllUsers property
can be set in the Properties window when a deployment project is
selected in the Solution Explorer.
Settings
False - The application will only be installed for the current user
and will not be visible to other users of the computer (the default).
True - The application will be installed for all users.
InstallAllUsersVisible Property
The InstallAllUsersVisible property for the Installation Folder user
interface dialog box determines whether the Install MyApplication for
yourself, or for anyone who uses this computer label and corresponding
Everyone and Just me option buttons appear during installation. The
InstallAllUsersVisible can be set in the Properties window when the
Installation Folder node is selected in the User Interface editor.
Settings
True - The Install MyApplication for yourself, or for anyone who uses
this computer label and corresponding Everyone and Just me option
buttons will be shown during installation, and the user's choice
determines the installation method.
False - The Install MyApplication for yourself, or for anyone who
uses this computer label and corresponding Everyone and Just me option
buttons will not be visible during installation."
================================================== =========
So here's Step-by-step what you do to install for Everyone as default
without the radio button choices appearing for your users who are
installing your product.:
1. Click on your setup project in your Solution Explorer.
2. Look in the Properties window and set the property InstallAllUsers
to be True
3. Click on the icon in the Solution Explorer toolbar that has the
pop-up tooltip "User Interface Editor"
4. Click on the "Installation Folder" item in the panel that appears.
5. Look in the Properties window and set the InstallAllUsersVisible to
be False.
6. Rebuild your solution.
