Office add-ins do not work with the click-to-run version of Office 2013

If you use the Office 2013 (or confusingly named Office 365 Home Premium Preview) consumer preview, you may find that add-ins and interactions with other platforms (e.g. the online Office 365 cloud offering) do not work.

The Office 2013 consumer preview is available from, and by default it installs the click-to-run web installer version.

What is the Click-to-run version?

According to

Click-to-Run is a new way of delivering and updating Microsoft Office to broadband customers using Microsoft virtualization and streaming technologies. Please read below about the benefits of Click-to-Run, as well as information you should know about a compatibility gap between Click-to-Run and some anti-malware solutions.

Click-to-run has a number of benefits:

  1. Click-to-Run is fast, letting you download and use Office in minutes.
  2. People using Click-to-Run get product updates automatically, with no need to download or install patches.
  3. Click-to-Run makes trying Office 2010 easy – it can be used side-by-side with your current version of Office.
  4. Click-to-Run products take up about half the disk space of normal products.

The Office 2013 preview uses a modified version of Microsoft’s App-V application virtualization technology, building on what was done for the Office 2010 version.

But there is a pretty major limitation with this version, which may make you want to use the full fat version.

This is due to the way that the applications are virtualized. If you try to run, for example, the Live Meeting Conferencing add-in for Outlook with Office 2013 click-to-run version installed, it just says that Outlook is not installed so that it cannot install it.

Likewise, if you try the excellent and essential ASAP utilities Excel add-in (

I have also found that you cannot open documents from Office 365. If you do you get and error message:


The only way around this as far as I can see, is to grab the technet version and download and install the full ISO. This resolved all these issues for me, but I appreciate not much use for those without technet. I have now installed the Conferencing add-in and can open documents from Office 365 with no issues.

Accessing Office 365 documents from Office 2013

The Skydrive integration with Office 2013 is really nice. But what about Office 365? If you try opening a document from your portal, you get an error saying that the correct version of Word is not installed.

But what you can do is just add your portal as a location in Word etc.

Click on Add a place, then Office365, and enter your credentials. You can then browse your document libraries from with Word, or other office 2013 apps.
