Hello Syed,
Thanks for your suggestion, but it not works.
on my local machine i have Windchill 10.1 and Windchill 10.2 instances with same port number , url n all.
i have to switch off 10.1 instances and start 10.2 instances to access Windchill 10.2, same thing for 10.1 Instances.
intrestig thng is, all Appletes from Windchill 10.2 are opens properly, but when i try to open Applets from Windchill 10.1, it shows AppleteInitilizationError.
Regards,
Vivek
