When I attempt to launch the program begins start up and then crashes. When I am doing this I am logged into Connection Client and I have checked that the Licenses are active. I have tried trouble shooting the problem with the procedure in the following like but it did not resolve the problem 

I'm not sure what the next steps should be, please help my project is moving into construction and I need to use to finish the design and provide construction support. 

I already instaled version, three times already and nothing works

I already did on regedit an nothing

I already uninstall C++ versions

I already rename folders on Users an nothing
