I\'m on a relatively new Windows 7 machine and in Notepad++ the TextFX HTMLTidy doesn\'t work. It says \"Unable to find libTidy.dll in the system path or C:\\program fi
It doesn't look like the libTidy.dll functionality was actually removed, just coopted by NppTextFX.
I enabled it in my installation of Notepad++ v6.1.5 by installing TextFX Characters via Plugin Manager. Two things happened after that: 1. NppTextFX.dll was copied in (Notepad++ install directory)\plugins\ directory and; 2. TextFX menu item is enabled between Run and Plugins, which now has the TextFX HTML Tidy option.
Also, there's no difference between the ANSI and Unicode versions of libTidy.dll in npp.5.9.bin.zip. I ran both through WinMerge.
