Issue Details

I have already used the code I developed using Veristand 2017 and TestStand 2017, and recently I updated to VeriStand 2018. Now when I load VeriStand 2018 code from TestStand, I see the following error. 

Error executing subset 'StartVeristand'. 
Error code: 1172; User-defined error code. 


This error occurs because TestStand cannot load a compatible version of VeriStand when you have multiple versions of VeriStand installed. To solve this problem, you should install only one version of VeriStand and uninstall previous VeriStand versions.

Additional Information

The VeriStand Steps for TestStand is a set of custom TestStand step types initially developed by NI R&D used to automate VeriStand from a TestStand sequence. However, this tool has been deprecated and is no longer supported by NI. Its use is no longer recommended and it is provided strictly as is.

Moving forward, please use the ASAM XIL Steps for TestStand , which can be installed via NI Package Manager.
