So I just downloaded Sigil 0.9.7 and upon running it, nothing happens (visually). Bypassing the launcher and running sigil.exe directly I get an error message about a missing dll.
By installing KB2999226 ( https://support.microsoft.com/en-us/kb/2999226 ) : Windows Universal CRT, and then running the launcher, all is fine.
Might want to mention the dependency or include the required RTs locally
