Thanks for the warning.
Are there any "Known Problems" with this combination or is just the
standard warning on not to mix versions?
There are problems with which program will be called on to use when
using a browser. There can be installation/de-installation issues. Since
it is Reader and Acrobat, you shouldn't have the issues some people have
with the MS Office plug-ins.
thanks for staying with me.

I can easily imagine that :-(
There are serious problems even with the Reader and Acrobat on the same
version level 8.x - under Vista as well as under XP.
As I want to load the Reader when opening mail attachments (WinMail) on
my Vista machines I had assigned the Reader as the standard application
to be launched. I took me weeks and only with the aid of an MVP and
several iterations I was able to fix the registry entries.
AFAICS the Adobe Reader and Acrobat install routines create serious
mistakes in the relevant registry areas.

What do you mean by the latter?
When you have two different versions of Acrobat installed, both versions
want to install their office plug-ins for created pdfs from the office
applications. If it is Reader and Acrobat only Acrobat has a plug-in for

Thanks, Mike, understood.
In the meantime I managed to find an updated version of Adobe's TechNote
"Acrobat product interoperability"
Having read it several times the situation to me seems clear as mud.
The table shows that the Reader 9 would be *allowed* in combination
with any version of Acrobat > 6.
OTH the document says:
"... Acrobat and Adobe Reader have numerous components
that have similar functionality and can cause conflicts
on a machine. The most prevalent among these conflicts
involves the plug-ins for rendering PDF files in the
browser, PDFMaker inside of Office Applications, and
the Adobe PDF printer ..."
and as examples mentions:
" ... Acrobat 8 with Adobe Reader 9 or
Acrobat 7 with Adobe Reader 8 ..."
Allowed is not the same as supported. I believe that there are fewer
problems with Reader 9 coinciding with some earlier versions of Acrobat.
Adobe cannot overcome all the problems that arise from doing so since
they are Windows issues more than Acrobat/Reader ones.
