Issue Details

My LabWindows™/CVI™ application runs without errors on my development computer.  However, when I try building an executable and running it on a target computer, I receive an error that says Windows can't find the cvirte.dll or that the cvirte.dll is missing. Sometimes, I receive the error the executable is linked to a missing export: cvirte.dll

Solution

This occurs because the target computer is missing the LabWindows™/CVI™ Run-Time Engine. There are two ways to resolve this.
  • Download and install the correct version of the LabWindows™/CVI™ Run-Time Engine on the target computer. The version of the Run-Time Engine must match the version of LabWindows™/CVI™ development environment you are using. 
  • Include the Run-Time Engine in your LabWindows™/CVI™ EXE distribution by building an installer.
    • LabWindows™/CVI™ 8.0 and later
    1. Select Build >> Distributions >> Manage Distributions
    2. In the Manage Distributions dialog box, select your distribution and then click Edit
    3. In the Edit Installer dialog, choose the Drivers & Components tab
    4. Check the LabWindows/CVI (Shared) Run-Time Engine option
    • LabWindows™/CVI™ 6.0, 7.0 or 7.1
    1. Select Build >> Create Distribution Kit
    2. In the Create Distribution Kit dialog box, choose Full Run-Time Engine for the Run-Time Engine Support option
