And yes, I am doing that. I tried elevating from a user account and from an Administrator account. Neither one would successfully register all users.
Install from user account, uncheck start TCMD, right-click tcmd.exe and “Run as Administrator”, enter admin user/password, click “Register”, enter code & check all users box, shows as registered, exit TCMD, start as regular user, not registered.
Install from admin account, uncheck start TCMD, right-click tcmd.exe and “Run as Administrator”, click OK, click “Register”, enter code & check all users box, enter code, shows as registered, Log off admin account, log in user account, start as regular user, not registered.
