Hi all,

I want to write a Wix Extension, which provides an ability to add something
to the registry on install, and remove it on uninstall.
But 'deferred' Custom Action, which should be the right point to modify the
registry, does not do the work. Registry does not get updated.
I am only able to modify the registry during 'immediate' CA.
What's wrong?

<Fragment>

    <CustomAction Id="RegEditPrepare" BinaryKey="Some.CA"
DllEntry="RegEditPrepare"
                  Execute="immediate" Impersonate="no" HideTarget="yes" />

    <CustomAction Id="RegEditPrepareUninstall" BinaryKey="Some.CA"
DllEntry="RegEditPrepare"
                  Execute="immediate" Impersonate="no" HideTarget="yes" />

    <CustomAction Id="RegEditExecute" BinaryKey="Some.CA"
DllEntry="RegEditExecute"
                  Execute="deferred" Impersonate="no" HideTarget="yes" />

    <CustomAction Id="RegEditRollback" BinaryKey="Some.CA"
DllEntry="RegEditRollback"
                  Execute="rollback" Impersonate="no" HideTarget="yes" />

    <CustomAction Id="RegEditUninstall" BinaryKey="Some.CA"
DllEntry="RegEditUninstall"
                  Execute="deferred" Impersonate="no" HideTarget="yes" />

    <InstallExecuteSequence>
      <Custom Action="RegEditPrepare" Before="RegEditExecute">
        NOT Installed
      </Custom>

      <Custom Action="RegEditExecute" Before="StartServices">
        NOT Installed
      </Custom>

      <Custom Action="RegEditRollback" Before="RegEditExecute">
        NOT Installed
      </Custom>

      <Custom Action="RegEditPrepareUninstall" Before="RegEditUninstall">
        REMOVE~="ALL"
      </Custom>

      <Custom Action="RegEditUninstall" Before="StartServices">
        REMOVE~="ALL"
      </Custom>

    </InstallExecuteSequence>

  </Fragment>

Thank you in advance
