License Key: Development vs Live Functionality For Old License

    Hi there,

    My team has an active license key (call it License A) for version 7.2.3 of the following GrapeCity packages:

    • “GrapeCity.Documents.Imaging”
    • “GrapeCity.Documents.Excel”

    This key is currently used for any new deployments of code.

    We have an older deployment currently live on an older version (6.2.5) for the same packages above, which uses an older license key (call it License B) for the older version.

    When trying to create a hotfix for the older deployment, I am unable to test locally because we run:

     GrapeCity.Documents.Excel.Workbook.SetLicenseKey(License B) 

    On startup, which is currently failing with an error of: “The license key is not valid for this version. Please contact sales to receive a valid license key for this version”.

    Is this the expected behavior? If so, is it specifically because I am using it in a local sense?

    How is the older version with the older license key (License B) still running fine?

    Cheers,

    Brett.

    Hi Brett,

    This is unusual. If your project is using the v6.2.5 of the GcExcel package, your old license (License B) should work without issues. This error typically occurs when attempting to use a GcExcel v6 license with, for example, GcExcel v7 packages.

    Could you please share a sample project that runs locally with the v6.2.5 package and License B, but still throws an error? This will help us investigate further and provide better assistance.
