After switching from McAfee to MS System Center 2012 Endpoint Protection the Launch Report button is missing from the test set window and the test instant property window. Any ideas on an exclusion or port setting that needs to be added to the security software to cure this?
The issue turned out to be the latest MS security patch to the 2005 C++ Redistributable. It installs both 32 and 64 bit versions which can confuse QC. The fix for the issue is to delete all the Microsoft Visual C++ 2005 Service Pack 1 Redistributable Packages (both 32 and 64 bit) and reload the one that comes with the QTP installation and reboot the PC. We also have modified all our standard service scripts to not push updates for the 2005 C++ packages.
