v220.127.116.11 Viewer seemed to install OK on one W7 machine: It can see hosts (all still at v18.104.22.168), and can control at least one of them.
However, on trying to do a remote install of the host to a test machine, with Remote Utilities security, I got a fail message:-
***** Start of log *****
Date: 16/07/2022 19:51:44
Checking files of the Host.
Host files not found!
This happened both when trying to install v22.214.171.124 host, and also later when trying to install v126.96.36.199 host.
I also tried remote installs from a different viewr which is still at v188.8.131.52..
Remote install of host v184.108.40.206 succeeded as usual.
Remote install of host v220.127.116.11 reported success, but I wa sthen unable to connect to that host. Further inspection showd that the host v18.104.22.168 had been uninstalled, bit v22.214.171.124 has NOT been installed in its place
Manual re-install of v126.96.36.199 using the .exe installer on that machine fortunately worked
I now see that v188.8.131.52 has just been released. I'll download that and see if these problems are also fixed and report back
