In one case my conclusion was that it happened because the machine's 
administrator had moved the "Program Files" directory to a different 
partition (which already existed and had other directories in it) AFTER 
the original install.

In the other case it seemed to be because the installation was an 
update/upgrade onto a partition which already had data on it, and the 
partition was not first reformatted/trashed.

I guess you could regard both of those as "customized installations". :)

These were some time ago, so these details are from my (unreliable) 
memory.  And, of course, there may be other circumstances in which it can 
happen as well - these are just the ones I 've come across.

The reason I came across the first one was because there was something 
using PROGRA~1 in its path and this turned out to NOT map to the "Program 
Files" directory... worse, the whole path mapped to an existing (but 
unwanted) path, which made debugging it painful. (Which is why I remember 
it!) :(
