New ATA Gateway installation fails

After updating your ATA deployment to ATA version 1.5, you get the following error when installing a new ATA Gateway: Microsoft Advanced Threat Analytics Gateway is not installed

ATA GW error

Workaround: Send an email to ataeval@microsoft.com to request workaround steps.

Deployment

The folder specified for the "Database data path" and "Database journal path" has to be empty (no files or subfolders). If it is not empty, the deployment does not progress.

Installation from Zip file

When installing the ATA Gateway, make sure to extract the files from the zip file to a local directory and install it from there. Do not install the ATA Gateway directly from within the zip file or the installation fails.

Configuration

After the configuration for an ATA Gateway is set, when the ATA Gateway starts for the first time, the "Not Synced" label is displayed until the service is fully started which may take up to 10 minutes the first time the service starts.

Network Capture Software

On the ATA Gateway, the only supported network capture software you can install is Microsoft Network Monitor 3.4. Do not install Microsoft Message Analyzer or any other network capturing software. Installing other software will cause the ATA Gateway to stop functioning properly.

KB on virtualization host

Do not install KB 3047154 on a virtualization host. This may cause port mirroring to stop working properly.
