hi ,

I bought a latest Robot studio 5.12 and installed on my PC. Every thing seems to be going good until virtual controller remained in a continuous start up state and never start.

Can anyone give a solution for this small bug?

thank you

Hi Ashwin,

Do you have a third-party firewall installed? If so, you might have to add some exceptions for the Virtual Controller communication to work.

regards,  
Johannes
