I installed JRiver 26.0.19. When I clicked on the Streaming and Cloudplay stuff, I had the problem where Chromium tries to install, but then hangs. I have had that problem from time to time on various computers and I know others have, too.
I searched the forums and tried a few things suggested. I wanted to post what finally seemed to fix it.
Matt had a post back on October 04, 2013:
"If you're having this problem, please delete this folder and try again:
C:\Users\[Username]\AppData\Roaming\J River\Media Center 19\Plugins\chromium"
I followed that path, but for my 64bit version of 26, and deleted the \chromium64 folder (it was empty anyway). Then Chromium seemed to install fine (reinstalling the folder and adding Chromium to it).
Just wanted to share in case others have this...
