SilkTest detected a Client/Server application.
The required Extension has been enabled.
There is only one solution for this problem with SilkTest testing tool. You have to recreate your windows user profile on the machine: Login as administrator, go to the User Profiles tool from the Advanced tab of the System Properties dialog box. Once you do, select your user profile from the list and click the Delete button. Log on again as you and this will create a new user profile.
P.S. If you want to save information from the profile, save that information individually i.e. if the you want to save your favorites copy the favorites to an other location and after deleting the profile copy the favorites back.
