Firewalls are hardware or software applications that exist to prevent unauthorized access to a computer or network. They may also block data transmissions, which can interfere with ProSeries communications. Allowing ProSeries files access through the firewall can eliminate error messages in downloading, updating, and licensing the program, as well as e-filing returns.

In particular, you may see the message Error downloading product inventory when trying to download and install ProSeries. A hardware firewall blocking communications most often causes this message. The hardware firewall may be contained in your router or modem, or a separate standalone device. Your hardware firewall must be configured to allow access to the files listed below to resolve the error.

Most firewalls have the option to allow or trust specific applications and files, but some may require more advanced configuration. Refer to your firewall manufacturer's instructions on how to configure it. If you're not sure how to configure your firewall, contact your local IT professional.
