How to change NTFS permissions for files or folders using Microsoft’s Extended Change Access Control List tool (xcacls.exe) tool

 

If you need a command-line tool that you can include in your batch files to change the NTFS permissions of files or folders, you can use the following tool from Microsoft.

For example, the command below gives

icacls c:\inetpub\wwwroot\files\ /grant mary:(M,WDAC)

NOTE: xcacls is DEPRECATED.  Please use iCACLS instead which comes bundled with Microsoft Windows 2003.

The type or namespace name 'Interop' does not exist in the namespace 'Microsoft.Office' error

 

I encountered the following error "The type or namespace name 'Interop' does not exist in the namespace 'Microsoft.Office' "

Found a working solution in one of the posts in this thread.

Here’s what I did:

1. Download the Microsoft Office 2010: Primary Interop Assemblies Redistributable at this link.
2. Installed the software; it would extract as a setup file named “o2010pia.msi”
3. Navigated to the “.NET” tab and added the reference “Microsoft.Office.Interop.Word”.  You can also manually add the reference under the

   <assemblies>

   tag

   <add assembly="Microsoft.Office.Interop.Word, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71E9BCE111E9429C"/>
      

If all goes well, it should get rid of the error message just as it did for me :)

If you encounter this error "The type or namespace 'Packaging' does not exist in the namespace 'System.IO', here's an easy way to solve it.

Just locate the
