Given that the Office 2013 click-to-run installer allows no customisation of the installation, whatsoever, how can I install, or where can I find an installer for the Primary Interop Assemblies/.NET assemblies?

Other info:

This problem is inherent because I am using a PowerShell script that utilises Word Interop assemblies. It works under Office 2010 installs, but wiith Office 2013 I get an error. From research, it looks as though I need to install the Office 2013 PIAs, but cannot find how to do so.


I think you need to get a non-click-to-run version of Word/Office.

From MS's Configuring a Computer to Develop Office Solutions:

Note: Visual Studio 2012 does not support creating Office solutions when the development computer has a version of Office 2013 or Microsoft Office 2010 that was delivered by means of Click-to-Run.

Also, as you've probably found, when you try to "Change" the Office install and add the PIAs via Add/Remove Programs, the Click-To-Run version doesn't give you the kind of options required to add features (just 'Repair', and 'Repair Online').

Currently you can download the PIA's for 2010 (and earlier) as a redistributable, but so far there's no separate redistributable for the 2013 PIAs.

  • Thanks for the reply. This was my worst fear. I was hoping there was a workaround. As far as I can see, ONLY volume licensed customers can use MSI based installers. Would you happen to know anything to the contrary? – George May 13 '13 at 16:05
  • If you log onto your MS account that you used to register/install the Click-To-Run version you can download an .IMG file of the disk. Not sure it's going to help any though. – Ƭᴇcʜιᴇ007 May 13 '13 at 16:13
  • Yes I was already aware of that, thanks. I had also tried to install the 2010 and 2007 PIA redists, but to no avail; still receiving the same error from the PowerShell script. – George May 13 '13 at 16:20
