Is there a way to recover old posts from this forum?

I previously bookmarked a post from this forum that helped me solve citrix client crashes through a registry tweak:

I've since updated my Citrix client and need to reapply the registry fix, but the forum post with the details seems to have disappeared from this forum.

Google still lists the post in search results (with a slightly different URL):

But Google Cache doesn't seem to have a copy, nor does the Wayback Machine.

I searched this forum directly for relevant keywords but didn't turn up anything.

Can anybody point me to a copy of this post?
