Unity startup problem

last night i reinstalled my system after adding some new Hardware every thing is fine except unity the details are below

At first run the manual registration was not in option

Screen one

Screen two after clicking register

Screen three after clicking next

after clicking finish the program exits instead of running please help

i also remove the application along with the pace -anti pricey and then reinstalled it but no luck , i see reinstalling the os would be an option but every thing except unity is fine so i want a reasonable solution here
