Vista Tutorial - "the system administrator has set policies to prevent installation

I am using Vista Ultimate and have installed Adobe Premiere Elemnts 3 on it.
When I try to update Premiere with a patch I get a popup saying... "the
system administrator has set policies to prevent installation". I have tried
taking ownership of all the relevant files and making surethat they aren't
set as being read only. I have tried applying the patch as the administrator.
I have even triend turning off User Account Control. Nothing works however.
Any ideas as to what policy I may have set wrong?

Anyone?

I am having similar problem with installing itunes-- i have tried nearly
everything except for dropping my computer from a 100 story building.
Microsoft must have some type of policy that should be able to be disabled by
an administrator. Someone please help.

I found the answer myself. If you open the start menu and select run type
secpol.msc then OK. A menu will appear. Select local policies then secutrity
options. Scroll down to "user account control" settings of which there are
several. Diabling the very first setting is what finally worked for me.
Suprizingly enbough I had previously tried turning off User Account Control
the normal way but found it did not work. Thankfully it worked this way. Your
milege may vary.

I am using windows home premium and 'secpol.msc' is not available. That is
one of the 100 things I have tried. I wonder if those options are not
configurable on Vista Home Premium. Anyone?

I found out that it is true that 'secpol.msc' is not available on windows
vista home premium. the only workaround was to go through the command prompt
and activate the 'real' administrator account. when i did this my problem
was solved.

What exactly did you type to activate the 'real' administrator account?

To activate the 'real' administrator account do the following

1. Run the command prompt as administrator
2. Type net user administrator /activate:yes

To set the administrator password type

> net user administrator <your choice of password>
