I’ve just had to write some instructions about how to check if the Office Primary Interop Assemblies are installed – or more specifically, the Outlook ones. I thought that might be useful…

- Find your Office installation. Click Change.
- Choose that you want to Add or Remove Features and click Next
- Select that you want to Choose advanced customization of application. Click Next
- Expand the Microsoft Office Outlook branch and look at the item .NET Programmability Support. A little hard disk icon means it’s installed, a red cross means it isn’t, and a hard disk with a ‘1’ means that it’s not installed, but will try to install it the first time it’s used. It should look something like this (although the yellowness is to highlight the setting):
- Click to exit without installing. To install, you’ll need the appropriate disc.
