As I open the installation app, it pops up a window saying nothing. Then I click OK, it quits automatically.
Which TeamViewer Host version are you trying to install?
I guess it's the latest version but I don't know which version it is because when I download it from teamviewer official website, it doesn't indicate its version. If you need to know its version, can you tell me how to find it?
If you tried with the one from our website, then it is most probably the latest one.
Have you tried to look in the TeamViewer related files in the registry? If you find any, please delete them and try again.
You will be able to find them as described here:
I deleted every related files in the registry and restart my computer, but I still cannot correctly install the host. The same prompt shows up again.
I figured out the full version and host cannot be installed at the same time and that's what caused this error.
Thank you for your update! ✌
