We have three variants of the current version (v100) of ErrorTrap available for download. There is one for each of Patch 1.69/Origin, 1.67/Steam, and 1.67/Everyone Else.

(scroll down a bit to get to the three download buttons, they are the colored circles showing the three different icons)
The three variants are exactly the same functionally, except that they each look for and verify the game's internal build number. If the wrong one is used, nothing bad happens because the patch levels in this case provide the same game files but an unnecessary warning will appear upon starting up the game that the core version is incorrect or outdated.
