Yes, it is very easy to use. They provide great support and release updates every few weeks. I am very happy with it... You can download trial version from: http://www.advancedinstaller.com/downloads/advinst.msi

I switched to AdvancedInstaller (www.advancedinstaller.com) when Windows Vista out... They are dedicated on Windows Installer (MSI) installers... and it costs less then Wise and InstallShield... Serhiy Horobets
