After I install from the original CDs and run the English pach to version 1.01, upon launch I get an error message, inexplicably in Polish, notifying me that the game was not installed properly and that I should install it. This happens both before and after a NoCD patch is applied. I haven't tried the version from Steam, but I'm not buying it again unless someone else verifies that it works. I'll keep tinkering with it to see if I can make it run.
