Yair Altman (4 days 15 hours ago): Nicholas – yes, I used it in a compiled Windows app using R2022b (no update). You didn’t specify the Matlab code location that threw the error so I can’t help...
Nicholas (5 days 12 hours ago): Hi Yair, Have you attempted your displayWebPage utility (or the LightweightHelpPanel in general) within a compiled application? It appears to fail in apps derived from both R2022b...
