Duplication of Squad components

[Fizwalker]

I've seen other threads concerning this issue, and I've read that if one can run the updater that comes with the game, you can eliminate the issue. However, I purchased KSP through Steam, and while the Squad's launcher is included, apparently the updater is not. (I've been looking in the root KSP directory for it, so maybe I just haven't found it, and the button in Squad's launcher is greyed out.)

Is there a way to get Steam to update these files, or a location where I can get Squad's KSP update program? If there is a way, I would love to find a solution that doesn't involve downloading the game again.... If possible.

Thank you all in advance!

Delete the Squad folder from GameData, then use Steam to verify the integrity of the game cache. That will reinstall the Squad folder without duplicate parts.
