I have windows 10 version 1809 and I am trying to install visual C++ 2015. The installer says that the setup failed due to error 0x80070666. It says that their is a newer version installed. I tried uninstalling visual c++ 2017 and then reinstalling it after I installed vc++ 2015 but visual c++ 2017 just overwrites the vc++ 2015 installation and I cannot see vc++ 2015 in the programs list. I can only see vc++ 2017. I am trying to install the latest versions. Should I leave it like that? Also my windows is up to date.
