This is Quang from WebCatalog. I’m so sorry that the app didn’t work for you. There was a bug that prevented the app from working on Windows 7. It’s now fixed in v25.8.2. Would you mind updating and giving it another go?
Also, WebCatalog does support spell-checking and right-click context-menu. When you click “Try”, WebCatalog only provides you with a minimalist UI to test out the web app/website. The apps that are actually installed would have many more features.
These is also a bug in the licensing system which displays everyone as “Registered”. An update with fix will be available soon.
