It has hosed up all my runtimes... I uninstalled P11 It was version 11.0.2 . My P10 will still not load its library... P8 the same.... I have no access to any of of my librarys all the way back to P4 !!!!. Literally thousands of bucks of material I can no longer access.. ... If I can not get my runtimes back I will no longer buy a Damm thing from Smith Micro
