Having trouble performing an offline install of X-Pack (to do a POC of X-Pack with our new ELK cluster).

I've got the 5.4.1 zip downloaded into a local directory and the plug-in script seems to have found it, but I get a Java exception error I attempt to run it:

> .\elasticsearch-plugin.bat install file://d:/source/x-pack-5.4.1.zip

Any suggestions?

Can you try with something like:

```auto
.\elasticsearch-plugin.bat install file:///D:/source/x-pack-5.4.1.zip

```

Dang - I missed the third '/' in the file command switch -- that was the trick, thanks for the help (I was trying file://D:/source/x-pack-5.4.1.zip)
