What to do when I see a CreateUniqueTempDir() error message for my HTTP Full Webpage Sensor?
or set the Security Context setting of the sensor to Use Windows credentials of parent device.
When using Windows credentials of parent device, please make sure you enter valid credentials in the Settings tab of the PRTG device your sensor is running on. The Chromium engine will then no longer run under the Windows user account your PRTG probe is running on (by default, this is the local Windows "system" user account), but will run as the user you define.
