I doubt it's crashing -- it's probably exiting the session because you didn't have sufficient privileges. TCCHERE.BTM has to be run in an elevated session - right click on the TCC/LE icon, and select "run as administrator".
Authorizations are right.
I was able to capture the error:
Do you want to add a "TCC prompt here" entry to the Windows Explorer
