For some applications, you can set logging options by editing the Log Profile value manually through the registry. Editing the registry is the only way to enable logging for VB script messages.
Note:
Edit the registry only for messages that cannot have logging enabled through any other means.
CAUTION:
Modify the registry at your own risk. Incorrectly editing the Windows registry can cause serious problems that may require you to reinstall your operating system. Be sure to back up the registry before making any changes to it.
