sorry you did infact already mention the scanner details. i researched about
this on their website. to check the mimimum system requirements check out the
following link
http://konicaminolta.com/products/c...ge/dimagescan-elite5400-2/specifications.html.
the only thing i could find is that it is not compatible with fast user
switching. it does not tell if it needs to be completely disabled or what do
we need to do in any case. not much of a help anyways this site but you could
try to disable fast user switching and try to run the setup again.
to do this open up click on start click on control panel.
in the window that opens look for user accounts. double click on it to open
it.
in the window that opens under "pick a task" you will have an option that
will say change the way users log on or off. click on that and you should
have a window where you will find the second option that would be for "use
fast user switching" uncheck that and click on apply options button just
below it.
now close all open windows and programs and restart your computer.
now try to run the installation again. do tell me if it works.
