            vSpace Installation Recommendations

            When installing vSpace for the first time, it is always recommended to disable the firewall and delay the antivirus software installation until our platform is installed, registered and working in the Session Host.  This is further described here.  However, when this is not possible or when you are installing in working environments, please make sure to disable any Anti-Virus or Firewall software during the installation of our product.  Because of the nature and purpose of an antivirus software, even as we have tested with some brands, we have seen the potential of interference with the installation of our product.  
            After installation has completed you may re-enable Anti-Virus and Firewall software.  

            Troubleshooting Steps 

            If system instability occurs after installing NComputing vSpace, please try removing vSpace and any antivirus or security software present, and then reinstalling vSpace.  As mentioned before, after our platform is running well and registered, and if the system is stable in this configuration, you may re-apply the antivirus and security software, being mindful to observe any changes in behavior in your system.   

            In some instances, our tech support may require for you to remove your antivirus completely during the process of troubleshooting. 

            In any instance, all mentioned network configuration, antivirus, firewall, and security software will benefit from the adjustments below. Please set to ignore/allow/trust the following ports and executables:
