VCRUNTIME140_1.dll solution not found
Refer to the installation steps. If you only download VCRUNTIME140_1.dll , there will still be other errors.
1. Based on the reference link
of the previous solution on csdn , a collection of Microsoft installation packages is recommended here. After downloading and installing, there are still errors.
2. Solution based on the installation document. It is said that Microsoft Visual C++ 2015
is missing , but it is indeed missing through the control panel. However, because Microsoft Visual C++ 2017 has been installed before , 2015 cannot be installed. You need to uninstall 2017 first and then install 2015.
What to do if mysql is not cleanly uninstalled
Mainly deleting two aspects, one is the file path, and the other is the registry
. The recommended way to deal with it is to directly search globally and directly kill all the old versions of MySQL.
Global file search can use everything.
