I installed CS6, it opens but screen is frozen?
Which CS6 application is freezing?
Do you get any error message after that?
If you have any other CS6 application installed, try launching that and check if that opens fine or give the same issue.
Also, try restarting the machine and then check.
May i also know the operating systems that you are working on?
North America
Europe, Middle East and Africa
Asia Pacific
