Is there a way to install the release version without the patches?

[Jaws2002]

Hello guys. I got the digital download from Just Flight. Is tere a way to install the game again without the patches?
I tried twice but that bloody steam starts installing the latest patch without any chance to get the version from the actual install.
There's over 4 GB in that installer and I think it should be enough to get the game running, but you never get the option to install only that version.

I read on Steam help page that you can install of the disc some titles but I don't know if i can do it with this digital download from Just Flight.

I have another copy I preordered from UBI long ago and i think that would work the same way.

Anyone has any ideas?

thx,
