can't run draw test harness and samples anymore
two months ago I downloded OCCT 6.5.3 and tried to execute the samples and draw test harness. Everything worked fine. But now, I get this error message when I try to execute programs: the procedure entry point "??task_group_context@tbb@@QAE@XZ" couldn't be located in the dynamic link library "tbb.dll".
I reinstalled OCCT but didn't help. My OS is Windows 7 Professional 64-bit. Is it possible that an Windows Update is the reason for the troubles?
Please let me know how I can solve this problem.
Thank you in advance.
