Hello David,
Thank you for your post.
From within the Host, it downloads and then nothing.
There is no automatic mechanism to update manually from within the Host itself. When it comes to automatic Host update (well, "semi-automatic" because you still have to at least initiate the process) you should do it from within the Viewer. See
Updating Remote Utilities, Updating Hosts -> Method 1.
So I've saved the msi file to my pc and on completion, Windows 10 deletes it.
If you want to update Host manually on the Host computer itself, you should just download it from our site and run the installer, then follow the wizard till the end of the installation process.
I'm not sure I understand about deletion. Do you mean it's Windows Defender that deletes it? Currently, there are no information about Windows Defender false detections (false positives). There was one immediately after the release but Microsoft quickly fixed it.
Is it possible for RU to post a .exe file for 6.9 please?
We only distribute the installer files in the .msi format. But if you need an exe installer you can build it yourself in the Viewer using the MSI Configurator. See
One click installer.
Please, note that MSI Configurator is an advanced feature which might be overkill in your situation. If you just need update a single Host manually on the Host computer, all you have to do is to use the original "vanilla" Host installer from the site.
Hope that helps.
