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
Thanks for the catch. I've marked this as a bug and am building a fix.
I've built a fix, it will be published in due order soon.
