Outlook 365 or Click to Run and third party integration

Microsoft Office users that are running Office Click-to-run version may encounter issues with some Outlook add-ins and standalone software for Outlook. Some of the programs may not work correctly on this Office version.

Emailing from Evolve requires that the COM interop libraries (Microsoft.Office.Interop.Outlook.dll) for Outlook are present in the installation of Outlook. These are often missing by default in an installation of Office Click-to-run.


In this case the best solution would be to install the full version of Offic.

How to identify Click-to-run Office:

 

Option 1:

Click-to-Run is a software delivery and updating mechanism. Products delivered via Click-to-Run execute in a virtual application environment on the local operating system. This means that they have private copies of their files and settings, and that any changes they make are captured in the virtual environment. Click-to-Run is fast—users can start running an application within a short time without waiting for the entire product to finish installing. Updates are carried out automatically in the background, without requiring a user to first remove an installation or install patches. Click-to-Run products are virtualized and do not conflict with other installed software.

However, because a product delivered by Click-to-Run has private copies of all its files and registration, an add-in developer cannot determine the product's existence the same way as a product that has been installed on a client computer’s hard drive. Starting in Office, Click-to-Run is the default mechanism to deliver Office, and only a subset of Office customers can request physical media to install Office. Add-in developers should determine whether Outlook has been installed, and whether Outlook has been delivered as a Click-to-Run product.

In Office, 32-bit Office and 64-bit Office are available via Click-to-Run. The default delivery is 32-bit Office for 32-bit or 64-bit Windows. You can also obtain 64-bit Office for a computer with 64-bit Windows. If you would like to have both Office 2010 and Office on the same computer, the bitness of the two versions of Office must be the same.

To check whether Outlook was delivered by Click-to-Run on a client computer:

  • Verify if the VirtualOutlook key exists in the following location in the Windows registry:

    HKEY_LOCAL_MACHINE\Software\Microsoft\Office\15.0\Common\InstallRoot\Virtual\VirtualOutlook
    
  • The VirtualOutlook key is a REG_SZ value that contains the culture tag of the installed product language, such as "en-us".


Option 2:


If you have Microsoft Office 365 subscription or use its trial version, it most likely mean that your Office desktop applications are Click-to-run.

One of the ways to identify if you are running Click-to-run Office is by going to Control Panel > Programs and Features, selecting Microsoft Office and clicking on "Change". In the opened window you will see different options depending on whether it is a full or Click-to-run version.
