Installing SSF exe file in to Vista error

[wulf]

Some of my customers are complaining that my exe file created with screen factory pro
are not installing on Vista systems.
Solution:
In some Vista systems you unable to open or install the screensaver created with Screensaver Factory, this is due to the User Account Control (UAC) in Vista.
Workaround:
Right click the setup file and chose to run as Administrator.

In fact the Vista should display users a prompt with a choice Allow / Cancel. The only situation I see this can occur is if the admin has somehow blocked this choice for users or if the user is running in limited user mode.

This is the same as for installing *any* software program. Vista does not allow to install anything without administrative rights.
