【IT168 技术】exe在Vista或Win7下不以管理员权限运行，会被UAC(用户帐户控制)阻止访问系统某些功能，如修改注册表操作等;如何让exe以管理员权限运行呢，方法有两种，一个是直接修改exe属性;另一个是在程序中加入MANIFEST资源，下面分别介绍。
1、直接修改exe属性
1) 右击“exe”，在弹出的菜单中选择“属性”，出现的界面如下图：
2) 选择"Compatibility"项，并勾选"Run this program as administrator"项即可。
2、 在程序中加入MANIFEST资源
1) 打开Vs2005或vs2008工程，看在Properties下是否有app.manifest这个文件;如没有，右击工程在菜单中选择“属性”，出现界面如下图：
选中"Security"，在界面中勾选"Enable ClickOnce Security Settings"后，在Properties下就有自动生成app.manifest文件。
打开app.manifest文件，将
<requestedExecutionLevel level="asInvoker" uiAccess="false" />
改为
<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />

<!-- UAC Manifest Options
If you want to change the Windows User Account Control level replace the
requestedExecutionLevel node with one of the following.
<requestedExecutionLevel level="asInvoker" uiAccess="false" />
<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
<requestedExecutionLevel level="highestAvailable" uiAccess="false" />
If you want to utilize File and Registry Virtualization for backward
compatibility then delete the requestedExecutionLevel node.

</asmv1:assembly>
然后在"Security"中再勾去"Enable ClickOnce Security Settings"后，重新编译即可。
