CVI Execution Profiler not showing (need registry cleanup method)

I have installed CVI 2010SP1 / CVI 2012SP1 and Execution Profiler Toolkit and even though I call the function CVIProfSetCurrentThreadProfiling(1)/set profiling in build options, at the end of the program run, the Profiler does not show up. I tried to uninstall and reinstall all CVI+Runtime (except device drivers which are mandatory to be kept the same), but this did not solve it. Please tell me which registry setting or registry cleanup tool I have to use. Thank you.
