    I’ve successfully linked and used the full api. However, when opening the LabVIEW application again the tlb needs to be relinked. Is there a way to register the tlb?

    Using regasm.exe gives the following error:


    C:\Windows\Microsoft.NET\Framework\v4.0.30319>regasm.exe “C:\Program Files\Weisang\FlexPro 12\flexpro.tlb”

    Microsoft .NET Framework Assembly Registration Utility version 4.8.3752.0

    for Microsoft .NET Framework version 4.8.3752.0

    RegAsm : error RA0000 : Failed to load ‘C:\Program Files\Weisang\FlexPro 12\flexpro.tlb’ because it is not a valid .NET assembly


    The cmd prompt was run in admin mode.


    Suggestions are appreciated.

    Regasm.exe (Assembly Registration Tool) is used to register the contents of a .NET assembly, not to register an arbitrary type library.

    When you use the Automation API e.g. in a C# program, you add the link to the FlexPro.tlb as a reference. How LabVIEW handles the necessary metadata to access COM objects does not fall into the scope of FlexPro.
