How can I automatically enable a VSIX extension, when installing?

I've created a VSIX package that I install via a WIX-generated MSI.

However, when I install it, and开发者_运维技巧 look at it in VS2010, in the Tools > Extension Manager menu, it is [Disabled] and I need to enable it manually.

How can I avoid this?

** EDIT **

Here's what I did:

I tried adding capturing the VSInstallDir from the registry like this:

    <Property Id="VSINSTALLER">
  <RegistrySearch Id="VSInstallRegistry" Root="HKLM" Key="SOFTWARE\Wow6432Node\Microsoft\VisualStudio\10.0" Name="InstallDir"  Type="directory" />

I added the directory structure under target-dir like this:

    <Directory Id="TARGETDIR" Name="SourceDir">
  <Directory Id="VSINSTALLER">
    <Directory Id="Extensions" Name="Extensions">
      <Directory Id="Copy_CompanyFolder" Name="my company">
        <Directory Id="INSTALLVSIX" Name="app name">
        </Directory>
      </Directory>
    </Directory>
  </Directory>

And I added a CopyFile element to the component in the installation folder, like this:

            <Component Id="VsPackage" Guid="00000000-0000-some-guid-00000000">
          <File Id="VsPackageInstaller" Source="$(folder.prop)\extensionName.vsix"
                KeyPath="yes" DiskId="1">
            <CopyFile Id="Copy_InstallVsix"
                      DestinationDirectory="INSTALLVSIX" />
          </File>
        </Component>

And I added the true element to the manifest.

When I do this, the extension is not installed.

Any ideas why?

If you install your extension files to a directory you create under %VSInstallDir%\Common7\IDE\Extensions, it will be enabled automatically for all users. This is the recommendation for MSI-installed extensions.

Also, please be sure to add <InstalledByMsi>true</InstalledByMsi> to your vsixmanifest.

There is no need to run VSIXInstaller.exe or write registry keys to enable your extension (In fact, you really shouldn't do this.).

Use "VSIXInstaller.exe" tool from VS2010\Common7\IDE.

Also you can manually enable your extension by adding registry value to HKCU\Software\Microsoft\VisualStudio\10.0Exp\ExtensionManager\EnabledExtensions
