SEO Studio installer gets triggered when Microsoft Office applications are accessed.

Answer 1

 

When SEO Studio starts it triggers the Windows Installer in addition a dialog window opens and asks for the Microsoft Office CD or installation source to install some missing components. 
If you cancel the update, SEO Studio seems to work ok and runs fine, but every time you start SEO Studio, you get the same Microsoft Office installation prompts.

The solution can be found in a Microsoft support article titled ???Windows Installer starts and prompts for the Office 2000 source when you access the Dynamic HTML (DHTML) Edit control???

The short answer to resolve this issue is to configure the Microsoft Office installation to set the HTML Source Editing feature to either Not Installed orRun from My Computer.
