I'm having the same issue as others are discussing here. Windows installer
runs everytime a Office application is launched. I've got a clean install of
Vista, as well as a clean install of Office 2007. I've tried uninstalling
via the control panel (add/remove programs), as well as tried using the
Windows Install Cleanup Utility. Same result, after reinstalling, windows
installer runs everytime.

I've even tried installing the original beta, as well as Beta2TR, same
result with both. I have no other versions of office ever installed.

Any advice?
