Okay, I've been a bit lax. We renewed our license a while back and I updated all of my desktops to 2011 (limited by sister division not getting funding to update).
Unfortunately I've got an XP laptop that I just brought in to get all the updates before XP goes dark.
But the Customer Portal no longer allows download of 2011. Previously tech support said that downloading was the only way to get prior versions.
The only thing I can think is to look for someone who kept their old media to borrow and install from.
I'm currently copying my entire SW2011 directly from desktop to laptop in hopes that included in there was the entire original download.
