Is it possible to update to 1.5 on steam?

[CrazyCanuck]

A friend of mine wants to do a collaboration station, and he's running version 1.5 and cannot update. I use 1.5.1, but for whatever reason, mine won't accept his save files because they use a different version. I use the steam version, so I figured it would be an easy matter to downdate by one version to exactly 1.5, however, I don't see that version on the list I can choose from. Is it possible to get back to that version using Steam? If so, how?

Nope 1.5.1 is the best you can do.

I see no reason you couldn't open his save files. I suspect he can't open yours, though just changing the version number in the file may work.

"Can't update" huh? Makes one wonder why.

Why can’t this guy update?

You might be able to with Steam, but it’s a convoluted process. Google “Steam downloading old versions”.
