Guys, here is the powershell command to successfully deploy your infopath form (.xsn) file to Central Adminstration SharePoint using SP Management Shell.
1) Open SharePOint Management Shell as Run with Admin
2) write this command and click ok
Install-SPInfoPathFormTemplate -Path “C:\Users\hamad.nasir\Documents\InfoPathPublishedForm\MyInfoPathForm.xsn”
3) There will be a prompt which ask to perform the operation write YES and press enter
OR you can upload directly to CA – Manage form Templates if you don’t want to use above command.
Thanks
