How to Reset Unity User Preferences?

I’ve brought a project over from another computer, and getting this error, as Unity attempts to find the preferences on the other computer.


Could not determine preset file
location type


I’d like to reset the user preferences of this project, so it’s looking at this computer’s preferences, not the other computer’s.

How do I do this?

This drove me crazy for the longest time, with no answers anywhere online, but I finally figured out how to fix that same issue on my machine. You need to go to your registry, Computer\HKEY_CURRENT_USER\Software\Unity Technologies\Unity Editor 5.x, and open up all of the keys that contain “CurrentLib” (such as particleCurvesCurrentLib_h1743720187 on my machine), then edit the binary strings to point to the correct path. You can put your cursor where you want and use delete/backspace as well as type the characters you need to fix up the string.
