Hi, it's been awhile since you've been here but I'll post a comment anyways. The Mass Effect Mouse fix is not working on Windows 7 x64 with the Origin version, it gives an error about not being able to find a module but doesn't specify which module.
Yes, that is a known Windows 7 specific issue that was introduced with version v1.1 of the mod and which I never got around to fix. You can just use the previous version v1.0 and it should work.
Thank you, I will update the article to reflect that.
