Issue Details

When I am trying to run executable VI on a host computer I am receiving black window that is like Windows Command Prompt. It pops up for a few seconds and then disappears. I am using Sophos Anti-Malware software on my developer PC. What may cause that behavior?


It is common that executables made in LabVIEW environment are blocked by Anti Malware/Virus software. To try, if file is being blocked by Sophos, please turn it off and rerun the .exe application. If test passed successfully (exe can run after turning off the AV software), you can add exceptions in Sophos. Please visit Related Links section to get the instructions how to do it.

Additional Information

If you are experiencing same behavior but you own a different Anti Malware/Virus software, please check the troubleshooting and look for exceptions for your software.
