Need help removing defective libraries...

Projects General Guidance
13

Please note: I have uninstalled the ide from the folder c:\programs(x86)\arduino and reinstalled the ide
in a new folder called c:\programs(x86)\arduino2. It still thinks the library files exist and is looking for them where there is no directory. Also still claiming that multiple librares were found for LiquidCrystal_I2C.h.
