Hi,
Sorry that you are seeing this issue.
We seem to have lost you in the Live Chat session.
Can you please clarify if you are running any anti virus software? If yes, then which one.
If possible, please try disabling it and see if the engine starts. Restart the machine post disabling the AV and check.
If the issue persists, please reopen the Live Chat session to help us diagnose the problem quickly.
Apologies for inconvenience caused.
