Windows Vista and Windows 7 considerations
When Thin Installer finishes installing an update package with reboot type 1 or 4, the system reboots
automatically. If there are any update packages remaining to be installed, the program continues to install
these update packages automatically after the reboot.
With considerations for Windows Vista and Windows 7 operating systems, after you log in to the Windows
desktop, the UAC might stop the program from continuing to install the remaining update packages. To
install the remaining update packages, you need to manually click the Windows has blocked some startup
programs message on the system tray and select Run blocked program to run Thin Installer.
Note: If the Windows has blocked some startup programs message does not display on the system tray,
you need to manually run Thin Installer, search for the remaining update packages, and install them.
Important: If you have the UAC enabled and you are not a built-in administrator, you might lose
authentication to the UNC share folder. To prevent this, you must add a registry key by applying the registry
file named ForVistaUnc.reg in the folder where the Thin Installer package files are unpacked. Here is the
registry key:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system]
REG_DWORD "EnableLinkedConnections" = 1
Web server configuration
The IIS (Internet Information Server) 6.0 or above does not serve unknown MIME (Multipurpose Internet Mail
Extensions) types. When Thin Installer requests a MIME type that is not defined on the Web server, for
example, .sys, the MIME type needs to be added to the MIME type list on the Web server. To add the MIME
type, refer to the detailed procedure available on the following Web site at:
http://technet.microsoft.com/en-us/library/cc725608(WS.10).aspx
Best practices
For best practices of working with Thin Installer, see “Scenario 8 - Working with Thin Installer” on page 69 in
Chapter 7 “Best practices” on page 63.
Uninstalling Thin Installer
No registry keys or temporary files relating to Thin Installer are created when the program finishes installing
update packages. Therefore, to uninstall Thin Installer, you only need to delete the repository folder and all
related files.
