Hi everyone,
I just installed Japanese-typing ability onto a Windows 10 machine and I had trouble with it. For those of you familiar with Windows, this required a re-configuring of the DNS settings (which may be waaay too technical for some of you.) I had already manually set my DNS addresses and this was the problem. I changed the settings so my computer could automatically determine its DNS server addresses. Once I did this, I was able to finish installing the Japanese-typing ability.
By the way, after allowing DNS server addresses to be found automatically, I switched it back to manual, and it still worked fine. What a strange bug!
Hope it helps.
