if your try to write in a user folder (that is, not in read-only folder like C:\windows, C:\Program files, C:\, ...) you should not need this, and that could be too complicated to do (3 clicks instead of only 2 is too many)
I said that, because i hate when programs wants to have admin right while doing nothing that would need them (like rappelz ...) . If every programs use admin right only if they need them, even if you download bunch of viruses, UAC should be enough as a anti-virus (at least if there is no security flaw in the uac used by these viruses)
And if you want to automatically have admin rights, you should use a manifest file with
Code:
<security>
<requestedPrivileges>
<requestedExecutionLevel level="requireAdministrator" uiAccess="false"/>
</requestedPrivileges>
</security>
