Hello Bart,
Thanks for your reply. The Viewer is a Win10 Pro machine, and the Host is a Windows 7 Pro machine. I've emailed the logs and the screenshot to the support address.
Well received, thanks. I've forwarded the logs and other information to our development to see what they can say about this. Since remote upgrade from version 6.3.0.6 works ok in our tests, it could be something with specific PC configuration, security settings or something else.
Regarding the two-row toolbar - your window chrome (frame) looks quite unusual. Do you have any theme pack or something else that modifies default Windows window layout, controls etc.?
I'm a little hesitant about upgrading the Server module. With my luck, something will go wrong and all my Hosts will become inaccessible.
Do you have another computer to install the server on?
I have another Host that I can test upgrading with, a Windows 10 laptop that is right next to me. Do you recommend trying to upgrade just by running the .msi directly on the laptop, or try upgrading using the Tools > Upgrade outdated Hosts tool in the Viewer?
Actually, both should work. The Remote Install tool is just for convenience. You can, of course, run manual installation if it's possible (i.e. you can physically access the computer).
