Remote PC: Windows 10 running TeamViewer 8
PC1 / Site 1: Windows 10 running TeamViewer 9. Connects just fine.
PC2 / Site 2: Windows 7 running TeamViewer 9. Can't connect to remote.
PC3 / Site 2: Windows 7 running TeamViewer 9. Can't connect to remote.
PC4 / Site 3: Windows 7 running TeamViewer 9. Can't connect to remote.
PC5 / Site 3: Windows 7 running TeamViewer 9. Can't connect to remote.
Error messages (always both at all failing connections):
- "Remote running old version.."
- "Connection could not be established. Reason unknown."
Already tried reinstalling after settings removal / registry clean. Rebooting...
What else to try? As usual the remote PC is very far away so upgrading that is not an option (which is the reason for teamviewer usage anyway...)
