Device Automation Service Locks and Unlocks Without Warnings or Errors


Question / Problem: 

When testing a DAS robot in Design Studio, opening the DA workflow or clicking Prepare Execution (v11.x), the device locks for about 5 seconds, then unlocks.

Answer / Solution: 

Download and install Visual C++ Redistributable for Visual Studio 2015 (32-bit) from Microsoft. DAS requires this file and is installed via the Device Automation Service installer .msi file. In some cases, environmental issues may prevent this from installing.

If that doesn't resolve the issue, also try updating Java (JRE) on the device and retest.
