Device Automation Service Locks and Unlocks Without Warnings or Errors

3024366

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.

 

DAS 11.x:

Since Visual Studio 2015, Microsoft delivers one package for VS 2015, 2017 and 2019. It can be downloaded from official Microsoft website. Go to:

https://visualstudio.microsoft.com/downloads/

and find "Microsoft Visual C++ Redistributable for Visual Studio 2019" for x86.”

 

DAS 10.6 and DAS 10.7 installers have VC Redistributable 2013 and VC Redistributable 2015.

VC Redist 2013: https://www.microsoft.com/en-us/download/details.aspx?id=40784

All packages are 32 bit (x86).
