Starting from September 22 2008, Mail Server .NET and FTP Server .NET installers will work without problems on Vista and 2008 servers.

In earlier versions, there was a problem, which is described below:

The setup program uses so called "custom actions" to install the service part of mail server. It involves an access to the Windows registry, and if your Vista has User Account Control (UAC) enabled, it will not like it, and throw an "Error no 2869".

The simplest solution is to disable UAC altogether. It can be done by going to Control Panel - User Accounts, and selecting Turn User Account Control on or off, then unchecking an appropriate box. After doing that, the computer has to be restarted.

If you can not, or do now wish to disable UAC, then you will have to run the setup from the administrator console, even though if you are logged in as an user with administrator rights. To do it, follow these steps (assumed, that UAC is enabled):

• Download the setup program MailServerSetup.msi, and store it in some directlry, e.g. c:\temp
• Click Windows logon in the bottom left corner, and in the Start Search box type cmd.exe;
• Press Crls - Shift - Enter, in the Windows Needs Your Permisson to Continue box click Continue button;
• In the command prompt window, navigate to the directory where you have saved the setup file, and type MailServerSetup.msi, and hit Enter;
• Follow prompts to install the server;
• Go to the folder, where you have installed the server (by default, C:\Program Files\ArGo Software Design\ArGoSoft Mail Server .NET, find the file MailServerUI.exe, right click it, select Properties, then Compatibility tab, and check Run this program as an administrator checkbox in the Privilege Level section;
• Now you are ready to run the program from the shortcut on your desktop.
