win8.1, PHP7 failed to start. php-cgi.exe lacks api-ms-win-crt-stdio-|1-1-0.dll. I downloaded this from the Internet and it also prompted a startup failure
Figure 1, but I didn’t put this dll in. of.
Figure 2 is an error caused by putting a DLL on the Internet
It has been confirmed that this is caused by the poor compatibility of Windows 8.1 system, because it is very difficult to install VC++2015, and the installation always fails. It is caused by system problems. It is difficult to install even after trying various methods. It is recommended that if If you only need to use php7.0, it is recommended to upgrade to Win10. It is not a problem with the phpStudy tool, but because the system cannot install VC++2015. The test phpStudy2016 version also has this problem on Windows 8.1.
Please try to install the VC++2015 runtime library and try it after restarting.
