We are having the same issue that I previously asked about in case CAS-195381-H1L4V4 on yet another PC.
https://ko.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:
Infragistics4.Documents.Core.v16.1.dll
Infragistics4.Documents.Excel.v16.1.dll
Infragistics4.Documents.IO.v16.1.dll
Please let us know if you need any additional help.
I couldn't get the "gacutil /il assemblyList.txt" command to work but we were able to get the controls into the GAC using individual "gacutil -I <dll>" calls. Tedious but it worked. Many thanks!
