Microsoft is offering a new way to download and install products of Microsoft Office 2010. This technology is called Microsoft Office Click-to-Run, and this article discusses how Office Click-to-Run interacts with some external applications that may use Outlook 2010 to send email messages.
Introduction to Office Click-to-Run
Office Click-to-Run is a new way for broadband customers to obtain Microsoft Office and to update Office 2010. Office Click-to-Run uses the virtualization and streaming technologies of Microsoft.
Office Click-to-Run Technology
Office Click-to-Run products use streaming technology that is similar to watching a video on the web. When you watch a video on the web, you can watch the first part of the video before the whole file is downloaded. Similarly, you can start using Office 2010 before the whole suite or product is downloaded when you use Office Click-to-Run. Therefore, the rest of Office 2010 is being downloaded in the background quietly while you use one part of Office 2010.
Office Click-to-Run products also use Microsoft virtualization technology that stores Office 2010 in virtualized application space. This virtual space separates Office 2010 from the regular file system and from the other applications on your computer. This separation lets Office 2010 coexist together with any existing version of Office that is already installed on your computer. There are also other benefits to Office Click-to-Run.

To download Office Click-to-Run for Microsoft Office Home and Student 2010 and for Microsoft Office Home and Business 2010, download the installation files from Microsoft directly.
Note The Office Click-to-Run technology is also used in Microsoft Office Starter 2010.
When you use the Send To feature of an external application to try to send in Outlook 2010 that was installed by using Office Click-to-Run, you may encounter an error message that states no email program is installed.

This behavior occurs because Outlook 2010 that was installed by using Office Click-to-Run cannot be seen by some external applications. Therefore, the external application cannot use the Send To feature while Outlook 2010 is the default mail client.
When Outlook 2010 is installed by using Office Click-to-Run, the Outlook 2010 program resides inside the protected virtualized application space that was mentioned earlier.
To resolve this issue, either change the default email client to another email application. Or, remove the Office Click-to-Run installation of Office 2010, and then install the MSI-based installation of Office 2010.
