Visual Studio 2010 Setup Project 64 bit create reg

问题:

I have a 64 bit setup project with a 64 bit windows service exe and dlls. In my installer class i create registry keys with this code:

using (typeKey = typeKey.CreateSubKey(@"SOFTWARE\Folder\Folder\Folder"))
        {
            typeKey.SetValue("Type", 0);
            typeKey.Close();
        }

But it keeps creating registry keys at SOFTWARE\WOW6432NODE\SOFTWARE\FOLDER\FOLDER\FOLDER. Btw setup copies exe and dlls under 64bit program files folder. No problem in copying folders to 64 bit folder.

Any idea?

You are using .NET 4, use the new RegistryKey.OpenBaseKey() method and pass RegistryView.Registry64

This happens because your custom action uses a 32-bit process. Perhaps this article will help: http://blogs.msdn.com/b/heaths/archive/2006/02/01/64-bit-managed-custom-actions-with-visual-studio.aspx

Basically, you need to either make it use a 64-bit process or call a function that can write in the 64-bit registry hive.
