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
/Users/myUserName/Library/Preferences/Unity/Editor-5.x/Presets/Default
UnityEngine.GUIUtility:ProcessEvent(Int32,
IntPtr)

‘’.

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.
