The default location on a regular installation is in the folder
C:\Program Files\Microsoft Office\Office11\Library\Analysis
There will be 4 files in the Analysis folder.
ANALYS32.XLL
FUNCRES.XLA
ATPVBAEN.XLA
PROCDB.XLA
If not found there, suggest you try the control panel add/remove>change and go
in and remove the ATP installation then re-install.
Assuming you have the installation CD, of course.
