Solution
This issue is caused by Microsoft Visual C++ 2017 Redistributable (x86) and (x64) or Microsoft Visual C++ 2015 Redistributable (x86) and (x64) packages.

To fix this error, you need to uninstall Microsoft Visual C++ 2017 Redistributable (x86) and (x64) or Microsoft Visual C++ 2015 Redistributable (x86) and (x64) from your system and then try again to install SQL server 2017.
