Cannot enter a product key
posted

We are having the same issue that I previously asked about in case CAS-195381-H1L4V4 on yet another PC.  

https://www.infragistics.com/my-account/support-case/CAS-195381-H1L4V4

The Infragistics WinForms controls 2016 Vol 2 was installed as a trial, then two service releases were applied.  We're trying to enter the product key but it will not take.  It keeps telling us that the product key is invalid.  We tried other valid keys and get the same error.  One of the last recommendations in case CAS-195381-H1L4V4 was to copy DLLs from a "good" machine to the problematic machine and manually add them to the GAC and VS toolbox.  Do you have detailed instructions on how we can do that?

    Hello Steve,

    Here are the steps that you need to follow:

    1. Remove any previously installed version of Windows Forms 2016.2 on the target machine
    2. Copy the dlls from a good machine to a folder in the problematic machine (let’s say the folder is named “WinForms 16.2”)
    3. Inside the “WinForms 16.2” folder create a txt file with the names of all assemblies each on a new line. For example, you create the file assemblyFiles.txt and inside it add the files in the following format:

    Infragistics4.Documents.Core.v16.1.dll

    Infragistics4.Documents.Excel.v16.1.dll

    Infragistics4.Documents.IO.v16.1.dll

    1. Open a Developer Command Prompt (installed with any version of Visual Studio) as an administrator
    2. Navigate to the “WinForms 16.2” folder
    3. Run the command “gacutil /il assemblyList.txt” (This should add all the assemblies from the assemblyList.txt to GAC)
    4. Then to add the dlls to the VS toolbox, you can follow the steps described at https://www.infragistics.com/help/winforms/introduction-adding-controls-to-the-toolbox. The easiest method will be to copy the dlls from your “WinForms 16.2” folder directly into the newly created tab in the toolbox.

    Please let us know if you need any additional help.
