I found what seems to be 12.1 Service Pack 1 on my archive drive. There are two of them. I think the second one with "free" in the name is for windows. The other is for Linux. I believe, but I'm not certain, that these were extracted from the download bundle when I got them. I didn't try installing them now, although I'm pretty sure I did when I got them. AT least the LInux one.
Awesome! Much thanks for posting those. My friend said they're both Windows, not linux. He added them to his collection but is still on the lookout for "full linux archive of 12."
Note - I'm an innocent bystander here. I have an idea what the software is for, but never used it.
