CS0009 Metadata file 'C:\Program Files (x86)\LINQPad5\ClearScriptV8.win-x86.dll' could not be opened

lionel06

i install Clearscript package using nuget and try to test a C# code source find in the official documentation.
I have this error

then i copy the dll inside the LinQPad 5 directory at "C:\Program Files (x86)\LINQPad5"
and now i have this !

Is it a LinQPad problem or a ClearScript problem ?
Thank's
