Issue Details

I just installed NI FlexLogger and I am experiencing crashes when switching between the Channel Specification, Logging Specification and Screen tabs.


  • If you experience unexpected crashes when using NI FlexLogger or any of our other software, make sure your system has the requirements to run the software you are using. These requirements can be accessed through the software readme document for your specific version of FlexLogger.
  • If you are experiencing crashes when navigating in the software user interface or specifically switching tabs in the project workspace, you need to make sure that you have at least .NET Framework 4.6.2 installed on your computer, even though .NET Framework is included with the FlexLogger install.
  • If you are using a Windows 7 OS, there is a known issue with the Microsoft .NET Framework January 2018 Security and Quality Rollup which results in a TypeInitializationException error and crash. Updating the .NET framework security settings should resolve this issue.
