Parallel Studio XE 2019 install fail - missing AddTrust cert
I tried to install eval version of Parallel Studio XE 2019 on a dev machine which has no Internet connection. It complained with this message:
"An AddTrust certificate is required to install this software. The required certificate was not found on your system. Click 'Yes' to install the certificate and continue, or click 'No' to cancel the installation."
Because I have no Internet connection "Yes" does not work. Alas the message does not give me much information about the missing cert. Does anyone know what certificate I need??
