Memcache error on windows 10

Question

I use xampp and windows 10 64bit and my php version is 7.1.4 , I downloaded memcached-win64-1.4.4-14 and put it in C drive: C:\\memcached.
When i run this command:

c:\\memcached\\memcached.exe -d install

I receive this error:

failed to install service or service already installed

and:

c:\\memcached\\memcached.exe -d start

I receive this error:

failed to start service

Please tell me where the problem is? thanks.

Answer 1

我的情况是，我应该打开 cmd“以管理员身份运行”以运行这些命令。

Answer 2

Eventually the issue was solved! i should copy the memcahced folder in the xampp folder and then execute the previous commands.
It's over, hope to be useful to others.
