Thank you for your post.
And the "Update outdated hosts" selection in the viewer seems to be hit or miss - sometimes it works, sometimes not, sometimes if I run it three or four consecutive times for a given host it will finally work.
The Simple update feature works for version 22.214.171.124 onwards. If you attempt to update earlier Hosts, it won't work on them because older Hosts simply don't have the code that would process the update (make it happen).
Here is more about update and Simple update https://www.remoteutilities.com/support/docs/updating-remote-utilities/
These irritations have been pretty consistent throughout the last few versions (just updated to 126.96.36.199 tonight).
There were indeed some issues with MSI, update and Host not starting in the several recent versions and we fixed them. For example, see our Release Notes
for version 188.8.131.52.
What's the prognosis? I know this sounds like just a general rant rather than specific problems to solve, but I'm not imaging it and I really want to keep liking and using your software.
Try to make sure you update both sides - Viewer and Host - to version 184.108.40.206 and let us know if you find any issues.
