iTwin Synchroniser 1.1.48.0 Does not Start

HI ,

I have just started using iTwin Synchroniser.,
By double clicking the application icon , I am hoping to get a IMS log in page, but seems like nothing is happening,

Is there something else need to be done for running the app??, I can see four processes running under iTwin but I can not see any front end page to signin.

REgards,
Vivek
