You shouldn't need to, we hope.  Note this code is in
and the only arguments that can be corrupted are the cmd we build for
the child, the args to the cmd, the environment, and process attributes
(program type, standard input/output handles etc).

So your driver busted something; the question is, what?  Since we didn't
create it, you can presume we have no interest in debugging it :)  But
here's just a smattering of things that might help;

Lingering, corrupted system environment variables?

Permissions of the system account?  (Try changing the service to 'Logon As'
another user who you create and set up with Write permissions to the logs/

Corrupted msvcrt.dll?

Corrupted service?  Might have to uninstall the service, reboot, then
manually delete this key;
HKLM\System\CurrentControlSet\Services\[service name]
and reinstall the service.

So much for 'expertise' ;-)  Glad you found a more informed place to ask.
