So I installed both Standalone and a Win7 x64 machine at home and everything work.
Then I installed the same files on a Win10 x64 machine at my workplace. I could log into the Standalone version and everything works including the liveDB.
But on Rhino, I could not log into Octane no matter what. I am running Rhino SR13 the latest from McNeel. It keeps giving me the 'could not connect to SSO server' message.
The weird thing is that on the Win10 work machine, I could still log into the Octane Standalone version without problem!? Is that a plugin problem or an Octane problem?
I have tried uninstalling everything and reinstalling everything more than 3 times and still no go.
I have also looked into my Windows Firewall and nothing from Otoy is blocked, nor anything from Rhino.
