Installation Error: “The package could not be installed”


When attempting to install WooCommerce USPS shipping plugin, I am greeted with the message, “The package could not be installed. PCLZIP_ERR_BAD_FORMAT (-10): Unable to find End of Central Dir Record signature

Can you please help solve this issue?

We noticed that you have the USPS basic version installed. We request you to deactivate and delete the basic version, and then try installing the premium version.
