Problem installing LRC v10.0

Can anyone please help me?

I am getting this error when I tried to update my LRC to v10., and I cannot even reinstall it either

The error message I am getting is : 

 - 2 fatal error(s), 0 error(s), 1 warnings(s) 

FATAL: Error (Code = 145) executing in command 'MoveDirectoryCommand' for package: 'AdobeLightroom-mul', version:10.0.0.202010011851
