So I found my old Sacrifice CD and CD Key upstairs, and installed them on my Windows 7 machine recently. I am wondering if there is any difference between an install from the old CD with Patch 3 installed, and the Gog version of the game. It seems to run fine, but there is no option for windowed mode.

Another thing I am wondering is if the widescreen fix from WSGF is a safe file to download. Chrome doesn't seem to like it. Thanks in advance if anyone can answer this for me.

it is likely safe but, many browsers dislikes files that is not being downloaded very often.
