try disabling the uac (user account control) that will solve most problems
and if you still can't install or do the run as... try switching your account
type to administator.

Yup, this is because the NT security model was developed for corporate
networks, and has inappropriately been dropped into place as-is when
NT was pushed at "the rest of us" as XP.

The NT model ASSumes each user will do a narrowly-defined range of
permitted activities, as befitting their job description.  That's fine
when you are being paid to do only work-related things on the
company's PC, but it becomes inappropriate when you own your own PC.

You may have avoided this problem in XP by simply running as
administrator all the time, but that undermines much of the security
that XP may have been able to offer you.  

Because consumers didn't take to using limited user accounts, and
pretending to be someone else when they wanted to admin thier own PC,
the software vendors catering for consumers didn't bother to embrace
the NT security model either.  So games, accounting packages, etc. all
required you to have admin rights in order for their software to work.

So it's "chicken and egg"; no-one in consumerland runs with less than
admin rights because their sware won't work, and no sware vendor
writres for reduced rights because everyone runs as admin anyway.

The result; consumerland misses out on most of NT's security
protection, and gets shot to pieces by malware.  The aggregate
firepower of consumer broadband, coupled with rampant malware
infection, leads to huge botnets that act as massive wild virtual
servers, currently carrying 95% of spam and being used as hacking and
DDoS tools against businesses and so on.

Vista tries to make NT security available to users who have not
embraced the "let's all pretend to be corporate serfs" model, i.e.
most of us, by retrofitting some of these protections to user accounts
that are set up with admin rights.

IMO, this is a great idea, and I also see in Vista the beginnings of a
move away from dumbo account-based rights (where everything that
happens in a logon session gets the same rights as you) towards more
consumer-appropriate per-program rights (e.g. IE 7 runs with less
rights than you do, thus limiting the harm web sites can do, and
programs have to ask you for permission to do admin things).

Ironically, Vista is seen as inflicting the NT user rights model on
consumers even as it moves away from this model, because for many of
us, it is the first time we've ever had to think about "admin rights".

It may be new to us, but folks from other platforms (MacOS, Linux)
that pride themselves on being "more secure" see these prompts all the
time, often with password required.  This process is pointed to as one
reason why these platforms are "more secure", whereas the same prompts
in Vista are complained about as being a meaningless nuisance.

DON'T "just" re-install.

Consider that these alerts become highly valuable when they pop up
unexpectedly, when sware running without your knowledge is trying to
rip into the system behind your back.

Think of this as like the discreet "beep" you hear from your home
burglar alarm every time you open a door to the outside of your house.
When it isn't you that's opening that door, then you may *really* want
to know that that is happening.

   Saws are too hard to use.  
   Be easier to use!

I am another person that is NOT happy with Vista however I had the premium
and upgraded to Ultimate now ACCESS DENIED is jumping up everywhere,then
these parameter incorrect or corrupted messages started.the people on the
network rolled my premium up and put it in a file and did what they called a
clean install.It worked for one day and I have hit every FAQ,posting
place,have ask windows & microsoft.they have a tech working on it no word
from him in over 24hrs.
People tell me to open User Accounts I have tried The only thing I haven't
tried is TNT I go C:\ access denied .go control panel user accounts
