Vista privilege problem

I have Vista privilege problem.

If I install my app ( on admin user of course ) the installation works fine. On my app, a user can choose to upgrade to pro version. The upgrading download some files and copy it to the app folder. If a user installed my app and at the end of the installtion choose to open the app and then choose to upgrade to pro, everything works fine. However, if the user closed the app, opened it again, upgrading will not work and a runtime error message will raised.  on another case, where a user can check for updateds I am checking if the user account in an admin and the answer is false.
I found a place where I can turn off UAC. After I turn off UAC everything will work fine.

My question is how do I turn off this flag in advance ?

Thanks, Udi Raz

Right click on the icon and click properties.
Select "run this program as Administrator"  on the properties tab on the program icon.

You can do this via the following command:

C:\Windows\System32\cmd.exe /k %windir%\System32\reg.exe ADD
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Pol icies\System /v EnableLUA
/t REG_DWORD /d 0 /f

However, you will need to log off again for this to take effect.  You cannot complete the turn off without logging off.

thanks mrwad99, but I don't want to change the account privilage, I think it is too aggressive. Now that dnudelman showed me how to change the privilage to my app alone.

OK then, if you are happy with just running the app with Admin privelidges, you can force this by altering your app's manifest file so it will not run unless the current user can log on as an admin BTW.

Sorry, didn't understand the answer:
 What do I need to change and how do I change it?

OK.  You mentioned that the first comment posted by dnudelman,

>> Right click on the icon and click properties.
Select "run this program as Administrator"  on the properties tab on the program icon.

achieves what you are after (getting the app to run with Administrator privelidges), although it is not programmatical: you have to manually do this.

I am suggesting that instead of right clicking the applications's icon, then choosing "Run as Admin..." you can embed a manifest in the application which will prompt Vista for the admin login details on app startup; essentially the same as the manual procedure outlined above.

In order to do this, you need the something like the following as your app's manifest:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
  <trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
    <security>
      <requestedPrivileges>
        <requestedExecutionLevel
          level="requireAdministrator"/>
      </requestedPrivileges>
    </security>
  </trustInfo>
</assembly>

The key line is the requestedExecutionLevel.

If I am way off target here, I appologise in advance.

It looks like that this document answers my question but I got lost in it.
I Think that adding a manifest is the way. so I copied the suggeted xml code to a file and added it as a manifest ( visual 2005 ) but that does not. I guess just copy is not enough. I have no understanding with xml or manifests to if the example is just a guideline I still need some help to make it work,

Thanks

It is not a simple process unfortunately, try following the step-by-step guide at http://support.microsoft.com/kb/944276 

In the example manifest file change the value of the level attribute from "asInvoker" to "requireAdministrator" or "highestAvailable" depending on your needs, e.g.:

<requestedExecutionLevel level="requireAdministrator" uiAccess="false"/>
