| ==Info==
| |
| This plug-in attempts to work around UAC installation problems on Win2000+. This plug-in allows your installer to operate with a user level process and an admin level process. This allows you to accomplish things that would otherwise be very difficult. For example, you can have an elevated installer instance launch another process as the user.
| |
| | |
| It all started in [http://forums.winamp.com/showthread.php?s=&threadid=265780 this thread]. It has been field tested with good results. It is still definitely in the beta stage (i.e. use at your own risk).

| ==Basic Example==

| ==Important Notes==
| |
| # If you need to use the UAC plugin for the uninstaller as well, you will need to initalize the UAC plugin for the uninstaller, such as through un.onInit.
| |
| # The outer/user process does not display any output as to what occurred. For example, if you have the outer/user process create a shortcut, and it fails, the inner/admin process currently visible will not display anything to indicate that a problem occurred. This is because the outer/user process does not yet communicate back to the inner/admin process.
| |
| # When a standard or limited user supplies administrator information into the Run As dialog, you may experience permissions trouble with any extracted file. For example, if a Windows 2000 standard user supplies administrator info into the Run As dialog, and the NSIS installer extracts an .exe file, then trying to call that .exe through an Exec can fail. If this is a problem, you will want to use the [[AccessControl_plug-in|AccessControl plug-in]].
