[zt]If you want to remove Windows Installer 2.0 engine on an NT4 machine. The first steps is to unregister the engine by typing "msiexec /unregister". Then rename msi.dll, msihnd.dll and msiexec.exe. Finally use regedt32 to rename following registry keys if they are still exist (you need to make sure Admin has full permission to a key before you are able to rename it):HKLM\SYSTEM\CURRENTCONTROLSET\ENUM\ROOT\LEGACY_MSISERVERHKLM\SYSTEM\CURRENTCONTROLSET\SERVICES\MSIServerHKLM\Software\Classes\.msiHKLM\Software\Classes\.mspHKLM\Software\Microsoft\Windows NT\CurrentVersion\Terminal Server\Compatibility\Applications\MSIEXEC
