Microsoft Vista has new security features that complicate
the process of installing software if you are not familiar
with them.
User Account Control Warning (when running set-up)
If you have User Account Control enabled (the default in Vista), then
when running an installer program (set-up program), you should get a warning
stating "An unidentified program wants to access your computer."
Choose Allow.
The reason for this warning is that installers require 'elevated'
administration privilege to properly
install an application on your computer. It's the same as if you right
clicked on the setup program and chose Run as Administrator. In Vista,
with UAC enabled, no program can run with administration privilege
(even from an administrator account) unless you approve it. This protects
you from inadvertently running an unknown program and giving it the ability
to change your system. It's up to you to decide
whether you trust the installer and to give it permission to run.
If you are confident with your judgement and you trust others (if anyone)
who has accounts on your computer, you might want to consider disabling
User Account Control (UAC) to eliminate the warnings. Your system will be
more secure in general if you leave UAC enabled, learn what all the
warnings mean, and use them wisely. But if the inconvenience is a greater
concern, here's a good article on how to disable UAC:
Disabling UAC in Vista
Unsuccessful Install with User Account Control Enabled
It's possible that your Vista system might not recognize our set-up
program as being an installer. This could happen if your Vista
system is configured in certain ways. In this case, you will not typically
receive a warning when running the set-up program. And the program will
not be installed properly, meaning you won't be able to run the program.
If this happens, run the set-up file again, only this time run it as
administrator. To run it as administrator in Vista, it's no longer
enough to simply log in to an administrator account and run the set-up
file. You have to actually right click on the set-up program and choose
"Run as Administrator". It will then install correctly.
If you see an error message the first time you run the program itself
(not the installer), you should run the program once using Run as
Administrator as well.
This program might not have installed correctly
If you have User Account Control enabled (the default in Vista), then
after running an installer program (or even after cancelling an
installation), you might get this warning from the Compatibility
Assistant. Once again Vista has guessed wrong and is warning you
unnecessarily. Choose "This program installed correctly".
Compatibility Assistant Warning (after running set-up)
Upon completion of the install, you may encounter another message from the
Compatibility Assistant implying (inaccurately)
that this is an "older" program and is not compatible with Vista.
This warning can be ignored as well.
