Unfortunately, HTML-Kit Tools appears to be no longer supported. Now two years with no updates/support it appears that Kit is now “End of Life” or abandon ware.
I have used and enjoyed HTML-Kit for a few years. The program suited my needs and served me well. For it’s time it was well supported.
About 6 months ago I started to casually look at editors. My requirements for an editor are quite simple, just looking for formatting and error checking/correction. I have no desire for a visual WYSIWYG editor.
If you are looking for another editor similar to HTML-Kit I suggest looking at the following:
3: RJ TextEd (https://www.rj-texted.se/download.html) Freeware editor. Supports HTML
All of the above, in my opinion are excellent editors with some unique features. You will find quite a few similarities to HTML-Kit Tools.
Personally I have settled on and purchased WeBuilder.
