T75-2017 BIOVIA Foundation 2018 Installer May Only Be Used to Upgrade BIOVIA Foundation 2017 and 2017 R2
Hub
If you use the BIOVIA Foundation 2018 installer to upgrade an existing BIOVIA Foundation 2016 or earlier installation, the installer will remove applications from the uninstall area of the Windows registry. This may make those applications impossible to uninstall or upgrade.
Resolution:
BIOVIA has documented that we only support using the BIOVIA Foundation 2018 installer to upgrade BIOVIA Foundation 2017 and 2017 R2 to 2018. If you need to upgrade an earlier version of Foundation to 2018, BIOVIA requires that you first upgrade to 2017 R2 and then upgrade to 2018. This requirement applies to Foundation installed on Windows or Linux.
This requirement applies only to upgrading existing Foundation installations and does not apply to new installations.
