Hi ArtLab- You can change the Windows Installer serivce to manual or disable
it entirely.

Control Panel, Administartive Tools, Services, Windows Installer, Startup
type- Manual or disable. Apply.

Changing this may solve the problem, but you may get some weird messages
when you add/remove software... just turn service back to automatic/manual.

More elaborate fixes that keep installer enabled include getting the latest
version of Windows Installer, re-registering Windows Installer, reinstalling
Excel, etc...

A few days ago I had to enable an add-in in my Excel program, specifically
the Analysis Tool pack. Ever since then, every time I start Excel, I get a
pop-up message which is titled "Installing components for Microsoft Excel"
and I have to wait till it goes through the process of "Installing:
Microsoft Excel Feature". I have tried unselecting the Analyis Tool Pack
and also ran a "repair" of my Excel installation, all to no avail.

Could someone please help me with this very ennoying problem. Thanks and
best regards,

Art
