Add-SPSolution : Failed to extract the cab file in the solution.

Hi, I have a simple powershell:

Add-PSSnapin "Microsoft.SharePoint.PowerShell" -ErrorAction SilentlyContinue
Add-SPSolution -LiteralPath "BNP.Cardif.Intranet.wsp"

The WSP file is on the same directory of the PS1 file, even thought it gives me the message:

Add-SPSolution : Failed to extract the cab file in the solution.
