My scenario is as follows. I have two Virtual PCs setup to develop the Outlook Add in in VS2005 (on the Build Machine) for deployment to Office 2003 (on the Install Machine).

Specifications are as follows:

Build Machine:
- Office 2003 PIAs installed
- Office 2003 installed
- Visual Studio 2005 installed
- VSTO 2005 installed
- .NET Framework

Install Machine:
- Office 2003 PIAs installed
- Office 2003 installed
- VSTO For Office Runtime
- Visual Studio 2005 installed
- .NET Framework

I've collected a bunch of information off the website and made an Outlook Add-in, set the security policy and ensured what I believe are the requirements for the Install Machine. On running the installation, it installs successfully on the Build Machine and Install Machine to the correct directory with correct caspol permissions (see extract below).

When opening Outlook why does it not load on the Install Machine? I have spent nearly a week trying to get this sorted, but with no success. Probably I've missed something basic.

Any help is GREATLY appreciated!!!

I look forward to hearing from you.
