I was able to install the latest 6.12 Beta 4 Host and Viewer programs, but the Beta programs are not fully vented so I will revert back to the 6.10 programs on Tuesday evening. I have 3 PCs that I have these on, which are all running Windows 10 Pro, Version 20H2, Build 19042.662.
I am running just the Host on the PC that I had the issue and I followed the following steps:
1) Followed the
Installing and uninstalling guide to uninstall Host 6.10.10.0 from the system.
2) Rebooted the PC into Safe Mode with Networking and ran the PC scan and repair solution,
Restoro. When finished, rebooted the PC into normal mode.
3) Disabled my antivirus software and installed Host 6.12 Beta 4. Upon completion rebooted the PC.
4) Created an exception in my antivirus software to avoid future problems from the Host installation folder.
5) Edit the Host to configure options and restarted.
6) Followed steps 3-5 above on my other 2 PCs and installed Viewer 6.12 Beta 4 as well.
7) Tested.
I have not had any additional installation issues. As stated previously, I will uninstall 6.12 Beta 4 and reinstall 6.10.10.0 Tuesday evening. I will update this post once I have completed the task. Thank you, Polina for your help.
