Sitecore Ship returning 404 when trying to install update package

Ship returning 404 when trying to install update package. Here is the script i'm trying for.

Invoke-WebRequest -Uri "http://mydomain/services/package/install" -Method Post -ContentType "application/x-www-form-urlencoded" -Body @{"path"="@D:\Users\Parsh\Desktop\test.update";"DisableIndexing"=$true} -UseBasicParsing -TimeoutSec 5000

And i'm getting below error. `

    404 - NotFound
    The resource you have requested cannot be found.
    We're sorry :-(

I'm using .net framework 4.6.2 and Sitecore 8.2 initial release. also doubled checked all the configuration, everything looks fine,

Appreciate your support.

Update : Attached screenshot:

It took some time to debug the issue as it was returning 404. Initially i thought that, resource itself not available.Later debugging the Sitecore.Ship framework i found that, 404 throwing bcz the path was not found. See screenshot below.

When i changed the location of the update file it worked.
