And how exactly you install/propagate the Host remotely? Do you have direct network connectivity with remote PCs to perform push-install? Or are you preparing a custom one-click installer package for someone to run on the remote PC?
I'm not sure what might be causing this problem, but it only makes sense to test the most recent version, which is 126.96.36.199 as of this writing. Could you please update your Viewer to 188.8.131.52. and also a few of your Hosts and see if the problem persists.
It says on the Starter page that if you want to upgrade to Mini you just pay the difference. I can't seem to find where to do that on the website?
Yes, that is correct. Currently, we are finishing preparing a special upgrade form which will allow our customers to order upgrade keys. Meanwhile, we can simply give you a 50% discount for the MINI license.
Feel free to start a support ticket and I'll send you your coupon code. Thanks!
Then it's either an outdated root certificate or intermediate certificate problem. As an example, here is how the monitor driver properties window looks now on our test PC, RU version 184.108.40.206 downloaded from the site.
