As I have written on this list and others, Acrobat is not
designed such that you may have parallel installation of
multiple versions of Acrobat and or mixed installations of
Acrobat and Reader on the same system while still allowing
for full functionality of all such versions. In addition,
you may find various types of crashes and anomalies.
The proper way to handle a "test" of Acrobat 8 (for example)
when you currently have Acrobat 6 installed would be to
totally uninstall Acrobat 6, reboot, and install Acrobat 8.
If and when you wish to go "back" to Acrobat 6, totally
uninstall Acrobat 8, reboot, and fully reinstall Acrobat 6.
No, I don't think this is ideal or even good. But that's
how it works, whether you or I like it or not! :-(

Subject: OT: Acrobat 8 Trial overwrites Adobe PDF printer driver
I had the following situation:
1. I have Acrobat 6 Professional up and running (with some
2. I want to give Acrobat 8 Professional a try, so I download
3. During the installation, I get a warning telling me that
version of Acrobat is already installed on my pc. Indeed,
version 6. I don't
want to remove it, so I click the Ignore button.
4. I play around with Acrobat 8 and discover the VERY nice
5. Next, I try to create a new PDF file (from FrameMaker) but
I get a
warning telling me that I have to activate Acrobat 8 first.
6. I check my Adobe PDF printer driver instance and see that
been overwritten by Acrobat 8. Is this correct?
7. I do want to upgrade to Acrobat 8, but later, so I still
need to be
able to create PDF files for my daily production work.
8. I take a chance and reinstall Acrobat 6 (Repair). Towards
of the installation procedure, I see that a new Adobe PDF
instance is being created.
9. I check the Adobe PDF printer driver instance and
properties, taking into account Dov Isaacs' very helpful
10. Everything works fine again.
So this worked for me to have two versions of Acrobat "next to
on the same pc, but I understand that playing around with the
printer instance can be tricky business. Or is there a better
(safer) way to
do this, apart from installing these trial versions on a
pc", which you don't use for production work?
