What should I do if the switch from win10 to php7 fails?

The solution for phpstudy2016 under windows10 cannot be changed to a higher version of php7.0 and above:

The author has always used phpstudy to create php and mysql under windows. The relevant test environment is very easy to use.

I don’t know if it’s because of the Windows 10 update or something else, but the PHP version cannot be changed. No matter how I install various versions of vc, I can’t switch to PHP7.0 and higher. The prompt that vc11 or vc14 runtime library is required always pops up:

I carefully studied the vc14 prompt, "Error 0x80070666, another version xxxx has been installed", and then looked at the system After checking all the vcs installed, I found that there is no 2015 (vc14).

But 2017 is the new version of vc14.

So, I tried to delete 2017 and then install 2015. Sure enough, the problem was solved, so I left a note to record it.

Postscript:

The author has tried to install a lower version of vc14 (2015), and then installed 2017. As a result, the lower version was overwritten.

The author has used phpstudy2018 and does not have this problem.
