Hi:
realize that this may not be too high on the priority list, but Textpad is one of my favorite text editors, and UK produced software. I tested by exporting the "Recent File List" and "Recent Strings" registry keys under "HKCUSoftware\Helios\TextPad 5" to a ".reg" file, then changing to "TextPad 4" and merging the file. CCleaner then works when Textpad is checked under the CCleaner Options -> Applications tab. Hence, looks like changing the code to recognize the "Textpad 5" subkey too is all that is needed.
Thank you so much for a great product.
Best,
