Issue: There might be a blue screen error after installing or upgrading ENS Threat Prevention. Issue: When you set a log location to a path with case sensitivity enabled, the error "Log path is invalid" displays instead of an error that the issue is due to case sensitivity.

When the faulty driver is replaced, future installations and upgrades don’t require a restart for this issue.
The restart must occur for the installation or upgrade to continue. If a restart is needed, a prompt displays on the endpoint to perform a one-time restart.
If it does, the utility replaces it to resolve the issue.
When you install or upgrade to ENS 10.6.1, the utility automatically detects whether the endpoint has the faulty driver. A utility, mfeepmpk_utility.exe, is included in the ENS 10.6.1 installation packages to resolve the issue with the faulty driver. Resolution: This issue is resolved in ENS 10.6.1 and ENS 10.7.0. The issue is timing related and doesn't always occur.
