Hi,
I am facing a similar problem.
The product configuration manager doesn't show install location of my
product and the update manager seems to ignore it as well. Thus I can't
install any feature from the update manager (I have 'foo' displayed as
target directory and can't change it to the appropriate one).
I've just read a few comments on the way to manage an external product
configuration, with a directory containing a .eclipseextension file. My
feeling is that the update manager and product configuration manager are
expecting this type of structure while I just want to use the basic
default location with a .eclipseproduct file.
Anybody have an idea of what is happening ? I've just exported my
product thanks to the product export wizard and I can't understand why
this location cannot be the default install location (as it behaves in
Eclipse IDE)...

I, too, had the same problem with updates on customer machines for my product. When they tried to update their software from my update site, they successfully navigated through the update wizard, but the target location on the location page showed 'foo' as the install location.
I was graciously allowed to use remote desktop to connect to this customer's machine and found that an over-zealous administrator had denied various access permissions on some specific directories for some users, including the directory where my software was installed.
I tried a test of installing my software in 'c:\test' and was successful in updating it.
I have to admit that I'm not an expert on Windoze domain user security but I asked the administrator to look into this in more gory detail.
I'm chaulking this problem up to some too-tight security on the computer system. Exactly what is needed and where is unknown, but unfortunately I need to move on to developing other features.....

Okay, more information. I have the same problem if I select 'Scan for
Updates' from the update configuration screen. I'm using version 3.2.1.
Note that updates work if I just use the normal Find n Install... action.
Here's what the workspace/.log file displays:
!MESSAGE An internal error occurred during: "Update Manager".
!STACK 0
java.lang.ArithmeticException: / by zero
at
org.eclipse.update.internal.ui.views.FindUpdatesAction$TrackingProgressMonitor.updateStatus(FindUpdatesAction.java:73)
at
org.eclipse.update.internal.ui.views.FindUpdatesAction$TrackingProgressMonitor.beginTask(FindUpdatesAction.java:53)
at
org.eclipse.update.search.UpdateSearchRequest.performSearch(UpdateSearchRequest.java:267)
at org.eclipse.update.ui.UpdateJob.runUpdates(UpdateJob.java:207)
at org.eclipse.update.ui.UpdateJob.run(UpdateJob.java:168)
at
org.eclipse.update.internal.ui.views.FindUpdatesAction$TrackedUpdateJob.run(FindUpdatesAction.java:93)
at org.eclipse.core.internal.jobs.Worker.run(Worker.java:58)
Actually looking at the code from eclipse, sure enough line 73 of
FindUpdatesAction.java looks like:
String perc = ((int) (workSoFar * 100.0) / totalWork) + "";
The 'totalWork' variable is passed in (effectively) from line 267 of
UpdateSearchRequest.java.
This is a bug in the Eclipse update manager code. 1) There's no
protection around this expression; and 2) the caller is passing in '0'
for total work to do.
