wbloore, before you run the app attached above please set your registry to
HKEY_LOCAL_MACHINE\Security\Policies\Policies\00001001 = 1 Application locking setting
HKEY_LOCAL_MACHINE\Security\Policies\Policies\00001005 = 40 Application locking setting
Regedit and Resco Registry will not let me change those values. I've tried loads of times. I've tried different versions of Regedit, including the HTC signed version. Still no luck. I've read that the C600 wouldn't allow application unlocking after installing the Push Email update. Is this the same sort of thing?
