Hi @whc.
I see this in the log file you provided:
Directory already exists: C:\Program Files (x86)\twxFoundationH2Trial-8.3.2\license_agreement
Have you tried to install multiple times? If on a previous attempt, you cancelled the install without letting it finish, remnants from that installation may still exist resulting in the issues you are now seeing.
If you were previously running the trial, and it stopped due to the trial period expiring, reinstalling will not allow you to start a new trial. In both these situations, you would need to reinstall the o/s.
If these scenarios do not describe your issue, please provide more details so we can assist you further.
Regards.
