MSI installation failing - advertised application may be unsafe

Hi,

Was not really sure what groups best to answer this so have posted it
to a few that seem relevant. I am trying to roll-out and Outlook
add-in which was coded using VB.NET and am having a few problems.

I have tried to automatically roll-out the MSI package on a Windows
2000 Server/Windows XP Pro domain using a group policy and though the
app is now showing up within Add/Remove programs, it is not actually
installed and is not available within Outlook as an add-in.

I next tried removing the program and reinstalling manually and during
the installation got this error message:-

"This advertised application will not be installed because it might be
unsafe. Contact your administrator to change the installation user
interface option of the package to basic"

Installation then fails but leaves entry in add/remove programs
anyway.

This package does work on the users who have domain admin rights.

So far what I have found on newsgroups about similar problems is:-

".NET framework needs to be installed" (this has already been done).

"Newer version of Microsoft Installer is needed" (not sure about this
one - I have found the installer on Microsoft's site, but only seems
to be for older versions of the OS, not XP Pro - how do I find out
what version a particular machine is running and where do I get the
upgrade??)

"This is a rights problem, check the user has admin rights on local
machine" - They do.

"Sometimes even if they have admin rights you need to login as
administrator to install package" - Tried this - same error.

If anyone has any other ideas/suggestions, they would be gratefully
appreciated as I am all out of idea's.

Thanks !!

Hello is this MSI package assigned or published.

Try to change the package installation user interface to basic instead of
Maximum. To do so right click the Particular Package Object, Click
Properties then in the appearing window, click Deployment tab, below change
the Installation user interface options to Basic.

This is another policy you can take use of also.

Always install with elevated privileges
Computer Configuration\Administrative Templates\Windows Components\Windows
Installer

Directs Windows Installer to use system permissions when it installs any
program on the system.

This policy extends elevated privileges to all programs. These privileges
are usually reserved for programs that have been assigned to the user
(offered on the desktop), assigned to the computer (installed
automatically), or made available in Add/Remove Programs in Control Panel.
This policy lets users install programs which require access to directories
that the user might not have permission to view or change, including
directories on highly restricted computers.

If you disable this policy or do not configure it, the system applies the
current user's permissions when it installs programs that a system
administrator does not distribute or offer.

Skilled users can take advantage of the permissions this policy grants to
change their privileges and gain permanent access to restricted files and
folders. Note that the User Configuration version of this policy is not
guaranteed to be secure.

Important

This policy appears both in the Computer Configuration and User
Configuration folders. To make this policy effective, you must enable the
policy in both folders.

Are you trying to install an application that has been advertised (i.e.
you're not installing it from the CD). Maybe MSI think that it's dangerous
in this case (installing a managed app) to show the user all the wizard
dialogs (where he could mess up the install). Can you set the UI level to
Basic (/qb) when you advertise the setup?
