Does htmlexe work for Windows 8 on tablets?

Before to pay for HTMLEXE last version, I would like to know, will my ebooks work on Windows 8 OS for tablets (tablets not PC, Windows 8 for tablets don’t use standard Win32 APIs, its use WinRT APIs)

No, HTMLEXE doesn’t work on WinRT: see the readme.htm that ships with HTMLEXE.
Maybe in the future we’ll ship a version for WinRT.
