Well, I had an issue with a custom Webpart, and nothing works. Then I had the brilliant idea of uninstall the solution, and try to reinstall (QA), because in Desenv and in my local machine the WSP works well
When I removed the solution by the "Central Administration/System Settings/Manage Farm Solutions" and tried to reinstall the same WSP, I take the error "failed to extract the cab file......" in the Sharepoint Managment Shell.
Thank you guys.
