DAO 3.5

Hi all,

My customer need to use DAO 3.5 on Terminal Server. I asked in TS Group
Community if i can downgrade the DAO version of windows server 2003 to DAO
3.5. A MVP said me that we can install both versions in the same server, but
he recomend me that ask in this group. He said me that DAO 3.5 is unsupported.

I need to know if we can install DAO 3.5 on a server with 4.0. My customer
needs this because they have a old application that use this version.

Do we need to downgrade the version of DAO on our server? Or, its possible
to instal two versions in the same server withot problems?

I copy the link of the TS Group Threath :

Thanks in advance

Jet 3.5 and 4.0 coexist side by side without interfering with each
other. Installing Jet 3.5 requires no alteration at all of the Jet 4
installation. Indeed, from Windows 2000 on, you *can't* make changes
to Jet 4, since it's an OS component and managed by the OS's file
protection.

But there's no need to worry about that. Install Jet 3.5 and don't
fret.

Note that it is good to check or apply the last Jet/DAO service pack
after installing Jet 3.5 on the server. The best version of Jet 3.5 was
the last one, and that may not be installed by whatever you find to do
the installation. (In particular it fixed a problem with memo field
corruption).

If you can't find something to do the installation, it is possible to just
copy the DAO and Jet files by hand, and register them using regsvr32
- fortunately, there is nothing magic about the installation, but you do
need admin privileges to install or register.

Note also that it would probably be a bad idea to try to use both
Office 2K+ and Access 97 on the same TS. Multiple versions of
Jet/DAO on TS = Good, Multiple versions of Access on TS=Bad.

You can install A97 to get the DAO/Jet files, but if you need A2K+,
make sure to run that as an administrator after installing A97: Your
users probably won't be able to switch between Access versions.

I don't see why this would be problematic, particularly if you
neuter the A97 re-installation process by following Michael Kaplan's
recommendation here:

In any event, I think Access was not the application that was using
Jet. Otherwise, there'd be no question about Jet 3.5 being installed
separately.

I followed the link back, and Access 97 installation had been
suggested as a method of installing DAO.

msaccess.exe registers some other stuff when you run it, even when
the SRG file is empty. Using an empty SRG file speeds up the
process, and protects the .mdb file association, but does not allow
you to run both versions on a fully locked PC, as a TS should be.

Also, there are other problems, for example read what he as to
say about ODBC.
