Ok, here is how you add the link to the 3.7 profile.

In the MEMBERINFO template

Find:
----------------------------

<if condition="can_moderate()">
<li class="thead"><a href="moderator.php?$session[sessionurl]do=useroptions&amp;u=$userinfo[userid]">$vbphrase[edit_user_profile]</a></li>
</if>

----------------------------
BELOW it add:
----------------------------

<!-- Start Admin Log In As User -->
<li class="thead">$admin_log_in_as_user_link</li>
<!-- End Admin Log In As User -->

----------------------------

Done!
