You can download the installer for the updated EWriter tool here:
http://download.ec-software.com/ewriter-setup.exe
Limitations:
- Some features supported only by Help+Manual, like links to EXE files, still require EWriter source files generated by Help+Manual itself, because the HTML code for the links is different. Even if you generate the source as WebHelp in Help+Manual and then use the standalone EWriter tool to compile the WebHelp to EWriter the links to EXE files won't work because they will be coded differently.
- You also still need to use Help+Manual for creating EWriter books with a separate viewer and book files. This is not possible with the standalone version.
