How to elevate c# application to update registry?

Question

Hi,

How do I elevate my application to update registry in windows 7 or in vista?

Answer 1

You'll need to use the .NET Framework 2.0 Configuration tool. Click the Runtime Security Policy node, and then click Increase Assembly Trust. You can also click the Evaluate Assembly to see what security policy your assembly is currently using.

Answer 2

Hi,

You can always run your c# application under administrator previllige, to do this add a Application manifest file into your project and change the setting as follow:

<?xml version="1.0" encoding="utf-8"?>
<asmv1:assembly manifestVersion="1.0" xmlns="urn:schemas-microsoft-com:asm.v1" xmlns:asmv1="urn:schemas-microsoft-com:asm.v1" xmlns:asmv2="urn:schemas-microsoft-com:asm.v2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <assemblyIdentity version="1.0.0.0" name="MyApplication.app"/>
  <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
    <security>
      <requestedPrivileges xmlns="urn:schemas-microsoft-com:asm.v3">
        <!-- 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.
        -->
       <requestedExecutionLevel  level="requireAdministrator" uiAccess="true" />
      </requestedPrivileges>
    </security>
  </trustInfo>
</asmv1:assembly>

Thanks
